Howard,

I think he is trying not only to gain the extra height, but also avoid 
proximity of the antennas and  conductive mast.

Perhaps another 10 foot of metal mast and standoffs to hold the dipoles 
  a foot or 2 away from the mast will work as well as anything and be 
good and solid.  He might have to change his antenna settings on various 
bands a bit, but that's no big deal.
