Ah, a nice idea, but I doubt it will accomplish what Pete is trying to
do (Or my limited understanding of OWL 2 is wrong---which is a good
hypothesis). http://www.w3.org/TR/2009/REC-owl2-syntax-20091027/#Metamodeling
says that when a  resource is mentioned as both an individual and a
class, the two mentions are interpreted independently.  My
understanding of that is that it will not be possible to put any
semantics on one of them that implies semantics on the other.

I'd be happy to have it explained why that understanding is wrong,
especially by a simple example that the Manchester OWL2 validator
agrees is OWL2 DL (or even better, OWL2 RL)
