I would not recommend that. That would re-introduce all the range-inheritance problems assocaited with datatyping. The basic idea of the current proposal is to keep range-assignment (ie rdfs:Range) and datatyping (rdfd:Range) quite separate, so you can have either one without the other (or both if you choose to). That is the only way I can see to allow the kind of Dublin-Core sloppiness in a rational framework.
