I think that's fine.

What's not clear to me is what exactly the rights of a Larger Work author
are.  If I want to incorporate Compatible Software into a GPL Larger Work,
I make a GPL-only copy of the Compatible Software under 11.3 and then I
can do it.  Can I instead dual-license the Larger Work under MPL+GPL,
assuming there are no other GPL-only components?
