I think it might be tough to paint with casein on suede and not have trouble. Stiffening the suede with hide glue would make it very hygroscopic, and I doubt it would work. It is possible to purchase casein emulsified with linseed oil, but it a isn't great. These same questions aren't really answered for depictions of tube-and-yoke armours, linen, etc. it would work best to dye the leather with cochineal, and seal it with the oil / wax mixture. Whatever you do, perform exhaustive tests on small samples, first, would be my suggestion.
