Why not?

The code is in svn and has been for ages, ready for forking.  Of
course, you can't change the license on the GPL code that you fork
without re-writing it.

The OSM data can be forked now as cc-by-sa as the data is right there
in planet, ready for forking.  You could fork data from an ODbL
project the same way.  Of course the same requirements for relicensing
would exist.  You'd have to essentially replace all of the data to
relicense the data.
