Good idea. I might use a piece of R45.
I used to occasionally see an R25 pointy top section attached to the top
of wooden utility poles. Same idea.

Along the save lines as what Steve said, you could even side-mount a short
section of 25G near the top and then be able to use an off-the-shelf rotor
plate, thrust bearing, etc.. We did this on a large-face tower (Stainless
G10) in order to hold a rotor and bearing for a 2 GHz steerable dish, and in
another case on a smaller tower (48" face) for a steerable VHF yagi. A
beefy collar suitable to hold a platform would be plenty strong enough to do
this on a monopole, then it would just be a matter of the attachment to the
25G, preferably grabbing all three legs.
Chain mounts are a cheap and easy way to add side-arms for VHF omnis and the
like anywhere along the length of the pole.
