No, not really.

The problem today is that when you include type traits you start depending 
on type traits, its dependencies, MPL, and _its_ dependencies, in turn.

If we put type traits and MPL into the same module, when you include a type 
traits header, you will depend on the exact same set. The module count would 
be decreased by one, but that's not the issue - the actual number of files 
will stay the same.
