I'd vote against a complete replacement and in favor
of a simple abstraction:

 - where to find files and

 - where to find navigation information

(such as can be extracted from .ali files).  Then it is still
possible to steer the compiler with a -P switch and maybe
a Lisp variable for the "external" project settings.

One reason is that GNAT project files are, well, GNAT specific.
They are not standard, though open, but other Ada compilers
use different project descriptions, use different options,
and so on.
  However, all compilers need to know where to find sources,
and many if not all produce information that can be used
for navigation.
