Excellent point Orchidflowerchild, and now that I imagine it, a nice big, flowering Cattleya amethystoglossa mounted on a gnarly piece of root stock, that would look really beautiful. Thanks for provoking us to think out of the box.
Kelly, There are a couple of things oyu could do:
1) remove the plant from the mount - this would damage the roots though
2) pot the mount - I've seen this on occasion, where the whole mount is potted. Depending on what the mount is, the mount breaks down and is discarded on the next repotting.
