Cochin project, should I add other breeds?

[PureFluff]

I'm going to start a cochin projects including gold laced and lavender Cochins. However, options are limited it seems. You can get lav Cochins in bantam, but I'm set on the end result being LF. So I was wondering if to get the bigger end result I should add, say, orpingtons. Wyandottes have way more common good gold lacing. The main problem with these is that they have no feathers on their legs. Brahmas?

What birds are the best to mix with Cochins to end up with a largish cochin in these colors?

Thanks.
