JPEG2000 supports an arbitrary number of channels/layers/whatever you want to call them. In fact, avatar bakes are five channels (the last two are used for bump-mapping and something else).
I agree though that you start to get diminishing returns from sculpties pretty quickly. Take a 128x128 five layer sculpty vs. a decently robust format built on top of a progressive meshing algorithm ( http://research.microsoft.com/en-us/um/people/hoppe/pm.pdf) and compare the vertices per second, error curves, and total download sizes.
