I'm not a lawyer, but I guess if two licenses are not compatible with
each other, this is most probably due to terms and content than due to
version number.

Can you quote the terms of both licenses which make your possibly
project unfeasible ?

Also, except in special circumstances, GPL terms are very simple : you
must allow anyone to redistribute your work for free (most notably
meaning no practicable commercial works), modified or unmodified, or
else, if you disagree, must not distribute anything at all. That's a
major point which any version of the GPL is unlikely to modify. Other
points and variant are mainly workaround dealing with technology
traps, like generic library instantiation, hardware keys, etc.

I guess your matter is more subtle than that, so there as well, can
you tell more about your requirements ?
