This is only my first year attempting to breed hybrids so take this with a grain of salt.

Without a strong number of snakes availiable to try a hybrid project with, I'm just going with what I've got as far as size for both sexes.

I'm planning on incubating the eggs as if they were the mother's full species.

Hopefully some others will chime in here as well and be able to help you out a bit better.
