Cochin x Longtailed breeds?

[Capricoco]

I have a gold laced Cochin roosters in with some silver duckwing Phoenixs and black Sumatras, I’m thinking about hatching some of the eggs and was wondering A) is this cross a good idea or is it a bit risky and B) what might the chicks from this cross look like? I’m also considering switching out the Cochin rooster for a barnevelder, so would that be better than the Cochin and what might those look like?

The Cochin x Sumatra offspring will be mostly black with pea combs and feathered legs. The multiple spurs should pass on but might be suppressed by unnamed genes and look like single spurs.

The Cochin x Phoenix offspring will be sex identifiable at hatch, the males appearing silver and the females gold. They will also be feather-legged.

Both crosses should get longer tails from the mother's side but probably not as long as the pure Sumatra or Phoenix.

Using a Barnevelder would give similar results except for the feathered legs.

Hmmm noted… how big do you think they’d be?
