For me, as a PD advocate, the more licenses you license the stuff under 
the better as it will combine the loopholes of every single one.

If, however, you intend to "protect" our data by putting it under a 
share-alike data, then any additional license you add weakens that 
"protection". Your suggestion would effectively kill the relatively 
strong share-alike element of ODbL that requires people to share the 
database *behind* a produced work, rather than just the work itself.

Anyhow - the contributor terms would technically allow OSMF to 
dual-license as you request, even without asking the mappers, so you 
just stand for election to the board and then effect that decision.
