Is is possible (has it been done), to dry sump a type1 VW

Yes. In fact, it's a standard procedure for high-output engines based
on after-market VW components installed in dragsters.

Entirely different subject, if you mean sustained flight whilst

cost of doing so is generally impractical for such a small engine.
