Start by looking on Craig's List. I just did and found a number of pigeons in my area. Also on the bottom of listing, there are listing that are further from local area. Some I would have to travel 100 miles.
I would just consider it a nice friendly Sunday outing. It would have to be a pigeon that I REALLY WANTED BAD, TO DO THAT MUCH TRAVEL. 
I think those feathers might be called a crest? They are adorable.
Not sure that the two varieties will pair up all that easily/willingly. My second flock of white pigeons were ether a poor blood line , or mixed variety. They would loft fly and return. They did not want to loft fly all that much ether. When they did, they just went onto the house roof and just parked there. In the eve they would fly back into loft. When a hawk would appear/visit, they scattered and usually some would not return. Hawk would not eat 3 at a time since multiples would not return. I never did see a hawk catch one BTW. I think they flew away like 7734 and were not able to find their way back. If you want your pigeons to keep returning, then I suggest staying with the homing variety. My second flock numbered "0" eventually.
I have never attempted what you are suggesting.
