I certainly would put another RX antenna w/voter on the same tower. Keeping in mind how often you've observed that just moving a few inches has taken your HT out of a null reminds you what just a bit of change in antenna position can make. (Presumably RX cavities, etc. are no problem.)
I have often used a voting RX for a 2 meter temporary repeater set up in an extremely weak-signal environment (see link below) and the antennas are very close to each other - on the same mast. Even though they are close, it's fascinating to watch the "voting action" occurring - with the LEDs switching between the two receivers. It's particularly interesting when, occasionally, two people will "double" and it'll switch from one person to another - when each person just happens happens to be in a null of one of the antennas:-) I've seen the trade mags claim a 6db improvement on overall S/N when just two voting RX's are installed with the antennas just a wavelength or two apart. Numbers like that are hard to quantify - but if a stacked yagi "seems" to have an extra 2db of "apparent" (over the 3 db or so one gets anyway) due to aperture - like some of the weak signal people say - then maybe that number is believable.
