Champagne and spider are lethal. The babies will die in egg or soon after hatching. I do not recommend pairing a champagne to this snake at all.
Different genes in the spider complex can cause varying degrees of wobble or be lethal when combined together. The only gene that seems to play nice and have no noticeable issue when you combo to spider is blackhead.
Albino is not the same as BEL complex. But when a visual BEL is also pied or albino they can have eye issues. So I would be very careful if you decide to pair to an albino. The issue list just says super lesser albinos, but you can search the sales records on MorphMarket and see it affects a large number of BEL albinos
There’s a lot of work you need to do studying the genes before you breed. It’s not as easy as just pairing any of them together.
I would suggest looking through the morphipedia here for starters.
Next is your allelic morphs:
