Sounds great to me, but it would be a shame to break up the 
stack just to feed the second radio on 10, 15, and 20. 
Another tribander in there would be great for the second 
radio, something like a KT-34 on a separate little tower far 
away, or a 2 el Steppir or Steppir dipole on the big tower 
at 80'. The Steppir would always be on a different band, so 
it wouldn't screw up the stack.
