Ideas On A Bantam Flock?

I think you'll be happy with Silkied Serama.

 

[Stick Chicken]

From your list, I have had sebrights, cochins, silkies, and d'uccles. In my experience, sebrights are pretty flightly, but I assume this could be tamed out of them. I think they are supposed to be fairly small, but my were bigger(didn't do so great in showing because of this).
Cochins are great and I love them. They are definitely NOT overrated. We recently sold a bunch, but we have ten right now, and they come in so many different colors. I have mottleds(black and blue), blue, black, and calico. I had a splash for a really long time, but unfortunately he passed last year. They are really friendly(the one who passed was my favorite chicken I had and I was devastated). If you want them for breeding though, I have heard that you may need to AI them. All of mine were naturally bred, but its what I've heard. If you want eggs out of your bantams, cochins are a bad decision because they only lay a couple eggs every so often(it has come to the point where they decide when I hatch eggs).
D'uccles are better egg-layers. They can be either docile or flighty, depending on how often you work with them. The roosters tend to be mean, but only during certain times in the year. I rather enjoy them and they seem fine with other birds and even a goose.(I'm still a little new to this breed since I only got some a few years ago)
I've had a lot of experience with silkies, and I know that they make terrible free-ranging birds. I say this because hawks love silkies(and not in a good way). It probably doesn't help that they have large crests that impair their eyesight and they can't fly. However they are really friendly. They don't lay very good, though. I have a silky who stopped laying after only two years. Also, be aware of their feet and mites. Due to feet feathers, leg mites have more access to the birds' feet and can cause problems (it's pretty easy to take care of though; just lather some vaseline on their feet).
I guess it really depends on why you want the birds, so I tried to include a little on each of the breeds.

I would leave out the Silkies and Polish. They get bullied for their crests.

My D'Uccles don't fight back, be forewarned that they get driven off food. My banty Cochin cockerel was a monster.

I'm having this problem right now. My d'uccle pullets do not fight for food. I am scared they would starve if I don't occasionally feed them separately
