If we had one test to verify that method foo() was mt-safe, and another
test to verify bar(), we still need a test that foo() and bar() are
mt-safe when used together. So that's another test to have. And it
brings us back to just testing all of the tests into one again.
Duplicate code or file dependencies could be a problem also.

Are you talking about modifying the nightly build infrastructure so that
it will invoke a test several times with different command line
arguments to run the test differently, or are you thinking about having
the test invoke itself with different arguments or something? I don't
think any option other than the first will work.
