BD15 vs Altec 416A (8ohm) (BD-Design)

My major concern is that, in a very expensive front panel, the cut out for one driver may be wrong for the other, but I guess I could make a cheap mock up.

Indeed... ;-)

Normally people seem to have something like a 15" bass, 8" mid and 3" tweeter on a single front panel. Is there any sonic value to be gained by mechanically isolating every drive from its neighbours?

If the mid is open at its back and the suspension is very flexible (like an AER) then yes, otherwise the diaphragm will vibrate with the same or even more excursion as the woofer at the same time.

Depending on a passive crossover too which acts as electrically damping but for the sound (read less distortion) it would be best to prevent this passive vibrating from happening.
