I am considering stacking a 15 meter beam above a 20 meter beam. Does
anyone have any idea what vertical separation I will need between the
two? I would guess that they would not interact much.

MOUNTING those antennas spaced 8 to 10 feet is about right.
Stacking, applies more to two similar antennas for the same band and switching
them for vertical pattern control.
