Your proposal is perfectly sound. A number of commercial manufacturers use
this approach. You want to keep the weight to a minimum at the top of the
mast, so use aluminium, not steel.
The great advantage of putting the support "pylon" on the mounting plate is
that you can pre-tension the support ropes before installation, and get the
boom nice and straight. Note that some ropes will stretch more than others
over time so you might want to test it at ground levels for a day or two.

Subject: [TowerTalk] Boom Supports
Good Morning, fellow antenna enthusiasts!
I have a question that I would like your expertise and experience with.
I would like to mount a long-boom 6 meter beam above my 20 meter
monobander. The mast extends about 6 feet above the 20 meter beam (I
know that this is pretty close spacing but it is all I can manage so it
will have to do!) As you can see, there is no room above the proposed 6
meter beam to mount a boom support guying system. I have been thinking
of mounting a short piece of angle iron, about 3-4 feet long, onto the
boom-to-mast plate so that I can provide a support point for the boom.
I understand that this is not an ideal situation but do you see anything
wrong with this approach?
Thanks in advance! Always enjoy the wealth of knowledge on this reflector!!
