[TowerTalk] Three Fixed Tri-Band Beams on One Tower?

This is, for the moment, a theoretical exercise.
I am exploring the concept of reducing the potential points of
failure and complexity. I do own a rotator. ;-)
10' is the separation number?
So if I stagger the beams vertically, each with reflector close
to the tower, 10 feet apart facing separate directions I should
eliminate the interaction?
This is more vertically efficient than 20 foot separation --
necessary when the beam centers are in-line.
So, how does this arrangement look:
Northeast on a mast at 65'
Southeast off the side at 55'
South off the side at 45'
I believe I have the necessary hardware to support the side-
mount beams should I elect to do this.
The strength issue of Rohn 25, Rohn 45, or Rohn 25 reinforced
with a second Rohn 25 is a separate consideration.
I also have a couple of 50' Rohn push-up poles on which I
could mount fixed beams ... but that adds coax routing complexity
and the push-up poles are much weaker.
