I don't think so, at least not if you were thinking about reworking the crank.
The crank needs this diameter, to accommodate the 5 fixing bolts for the
flywheel. Reworking the case would be the only option, if you were to keep the
wbx crank.

If you need a blown wbx, check this out:

 http://www.berlin-bear.de/golf/dokumentation_d1.html

This is a guy that is putting in a supercharged wbx into the rear end of his 1978
Thing. At this moment, he is only using the 2,1 MV engine, but he has a complete
2,5 Oettinger wbx, where he is planning to do his tricks. He is using the
Supercharger from the MB 230 SLK. Text in German only, but some pictures.
