Jay,
I like it!
How large is this stone? While it could certainly be used as a figure (somehow turtle springs to mind), it need not be. With a daiza that would cradle the raised portion, it could easily be a beautiful mountain view stone.
I don't know if you have seen this blog yet, but here are two links to Mas' Nakajima's suiseki art, and to Janet Roth's blog about it.
