I'd just publish the DL version at a known location, the full at the  
standard location, and use owl:imports to include the DL version in  
the Full version.

In OWL 2 you will be able to say something like:

import foaf (specifying the standard URI)
versioninfo foaf-dl (specifying the location of the DL) version.

or simply (and perhaps better)
import foaf-dl

On the question of discovery, I'm not aware of a mechanism, but it  
may be worth thinking about. But there shouldn't be a block to  
proceeding in the manner I suggest for the moment.
