As I understand it, this wouldn't be needed - it is not necessary to
make a separate release.  Any code under the LGPL can always be used
under the GPL by anyone, there are clauses in the LGPL which
explicitly allow this.

I'm assuming we are talking about version 3 of the GPL here, or
version 2 with the "any later version" permission.

Yes, I wouldn't see that being a problem.
