Copyleft licences (or a copyleft licence and a hybrid copyright/DB
Right/contract law conceptual approximation of sharealike) are
*generally* mutually incompatible as they require derivative works to be
placed under the same single licence.
You can however mash-up the produced work under BY-SA.
Creative Commons did put a mechanism in place with BY-SA 3.0 to declare
other licences "compatible" with BY-SA and allow derivatives to be
relicenced under them. But they haven't declared any compatible yet.
