This would be problematic for our own uses unless the CC-BY-SA / GFDL compatibility issues are resolved. The wording of the cc-by-sa requires any derivative works to be distributed "only under a license identical to this one"
The license could make a distinction between works which are direct derivatives, and separate works which are used in a way where one semantically depends on the other. In the second case, it could allow them to be under separate licenses, as long as all component licenses are free content licenses.
