I contacted the door mfg and
they can send me the bronze hinges to subsitute. However, since they
are installed, the thresholds can't be changed without removing the
doors and trim. Can I paint the thresholds and, if so, what kind of
paint will stick to the aluminum?

You have to etch the aluminum back to bare metal, then use zinc chromate
primer (yellow stuff) followed by paint of choice.

Have done all that, it will probably take less than 6 months to wear the
finish off back to bare aluminum, given the application.
