Sure, it'll work fine. Pick an electret mic type that Ashhar has
blessed, and adjust the mic wiring appropriately.
I think you can put the DC voltage onto the "hot" audio lead of the
3-wire XLR interface.
I've never tried it but I happen to have a rather nice XLR mic and
audio processing unit that came in a station purchase, and when I prep
my Heath DX-100 for operation, I'll definitely use this mic when I'm
not using one of my Astatic D-104s with a new electret element.
I'd mention -- back in the day I made a 5-pin DIN mic switchbox so I
could test and use all the old CB mics I'd collected over the years on
my Atlas 210X. Being able to switch mics on the fly was fun, and it
sometimes confused toe ham on the other end of the QSO.
