I say go for it if you really want to. Never hurts to try. I think it's always great to have long term goals if you're breeding.

However, all 4 of those are pattern morphs, and while some of the combos are additive, I think a lot of what makes each one great will get lost. It would be like putting paisley, stripes, polka-dots, and argyle patterning on a piece of fabric. But that's just my opinion.
