No, the timestamp in the .ali and the file timestamp have to match.

You can use GNAT Project for this sort of thing; for a while we built
AUnit with different options from the rest of the build because of the
numerous style warnings. And our setup is similar to yours (each
developer builds from source).

GPR in 3.15 was quite early, though would probably support this sort
of thing.
