I agree with Daisy. Probably separate pots in a single container. It sounds like a lot of work. I'm finally figuring out how to keep them all happy by themselves, I don't need a bigger challenge ;)
I have to make the most of my summers before I bring the plants back in for a tortuous NY winter indoors and my orchids would never tolerate the full sun my succulents love and I don't think my succulents would like the high humidity the orchids love.
Tiffany makes a good point- there are succulents that also grow in rain forests, but Ive never seen a christmas cactus (Schlumbergera) or rhipsalis potted in bark and they will both flourish in full sun that would burn the orchids.
