Yes a splash birchen will work the same. Only difference will be the offspring will have the birchen pattern.
You don't have to use splash but that will give you 100% blue offspring.
You can use a blue rooster and get around 50% blue and 50% black offspring.
Self blue is two copies of lavender on a black bird.
It takes a copy of lavender from each parent to make a self blue bird.
You can breed self blue to black and all the offspring will appear black but carry one copy of lavender. That what is called black split to lavender or a split.
Breed the splits together and you'll get around 25% self blue.
Breed a split back to a self blue and you'll get around 50% self blue.

Use your blue, black, splash or self blue ameraucana rooster with legbar hens
That will give you black or blue offspring. And sex linked. Males with head spots and barred. Females without head spots and non barred.
You should get muffs and beards and some with various amounts of crest.
Also they will all have pea combs and lay blue eggs.

I've seen two different definitions of "self blue". Most of the time I think it refers to Lavender chickens, totally different genetics than the B/B/S genetics. The other definition was "solid blue, no feathers with different colors". The breeder should know which it is.
The Lavender gene is a recessive gene that modified black to blue/lavender when it pairs up. A solid Lavender chicken is base black. If you cross a Lavender with a Black, you will get black but each offspring will have a recessive lavender hiding in the genetics. So if you cross the offspring back to a Lavender you will get some black and some lavender in the second generation.
The B/B/S gene is a partially dominant gene that also modifies black feathers. If both genes at that gene pair are B/B/S, then you get a splash chicken. If one is B/B/S one one is not then you get a blue chicken. If none are the B/B/S gene you get a default black. So if you cross a Splash chicken to a black chicken you will get a blue chicken. If you cross a Splash to a blue you get some splash, some blue. If you cross a blue to a black you get some blue, some black. If you cross a blue to a blue, you get some splash, some blue, and some black. If you cross splash to splash you get splash.
Both lavender and B/B/S only affect black. So if the bird has different colored feathers they will not be solid colored.
The legbar has the barred gene which is a sex linked gene. If you cross a no-barred black, blue, or splash rooster over a barred hen like the legbar you get a black sex link. The boys will have a spot on the head, the girls will not. The boys will feather out barred, the girls will not. One of the keys to making a black sex link is that you have to be able to see the spot in the down, you can't do that with all crosses. With yours, the black will probably be easier to see than the blues but you should be able to see it with the blues too.
The muffs are not sex linked but it is a partially dominant gene. Your Ameraucana should be pure for that gene (that means they should each have two copies) so their offspring will all get one copy from them. Your legbar won't have that gene so a cross between your Ameraucana and legbar should have a muff. But since it is a partially dominant gene instead of fully dominant the muffs will probably not be as prominent as on your Ameraucana.
The Lavender gene is a recessive gene that modified black to blue/lavender when it pairs up. A solid Lavender chicken is base black. If you cross a Lavender with a Black, you will get black but each offspring will have a recessive lavender hiding in the genetics. So if you cross the offspring back to a Lavender you will get some black and some lavender in the second generation.
The B/B/S gene is a partially dominant gene that also modifies black feathers. If both genes at that gene pair are B/B/S, then you get a splash chicken. If one is B/B/S one one is not then you get a blue chicken. If none are the B/B/S gene you get a default black. So if you cross a Splash chicken to a black chicken you will get a blue chicken. If you cross a Splash to a blue you get some splash, some blue. If you cross a blue to a black you get some blue, some black. If you cross a blue to a blue, you get some splash, some blue, and some black. If you cross splash to splash you get splash.
Both lavender and B/B/S only affect black. So if the bird has different colored feathers they will not be solid colored.
The legbar has the barred gene which is a sex linked gene. If you cross a no-barred black, blue, or splash rooster over a barred hen like the legbar you get a black sex link. The boys will have a spot on the head, the girls will not. The boys will feather out barred, the girls will not. One of the keys to making a black sex link is that you have to be able to see the spot in the down, you can't do that with all crosses.

These are self blue... meaning the breeder also have black splits so I think what you are talking about it’s a dominant gene
Self blue are recessive lavender on a black bird.
Self blue is what the APA calls the variety. Lavender is the name of the gene responsible for the color.
Outside the APA world many simply refer to the color as lavender.
It is a recessive gene and takes two copies to be expressed.
A black bird with one copy is called a split.
It just means although it appears as any other black bird that it carries one copy of the lavender gene.

So if I breed my self blue/lavender to the pure black... do I get any self blue and would the blacks be split?
