The the sort of quick solution that you will never commit? Then try it.
My bet is that, unfortunately, it will not give a very big speedup.
The big task of the collider is to sort bounds, and it has to be done
for all your elements anyway, since they can interact with other bodies.

Collider.cpp:13, this is where masks are compared in bool maycollide().
You could test bodies masks with a self-interaction mask there, the new
mask could be a member of the collider.
Maybe try the first method before deciding if it's worth the additional
test.
