I've had similar setups on one of my towers here at K8CC with good
performance. The mast was 1-1/2" schedule 40 water pipe with about 10'
sticking out of the tower. I had a 5L 10M beam (26' boom) at the top of
the mast with various VHF antennas below it. This setup lasted nine years
before a freak wind bent the mast. But note the big HF beam was at the
top. I learned my lesson and I now have it lower on the mast.
I would put the 6M beam at the top of the mast, the tribander at the bottom
(i.e., just above the tower top) and the 2M beam in the middle. My friend
K8MR down in the Cleveland has a similar setup, but he also wedged 222 and
432 yagis in there as well (on about 12' of mast).
