Maybe. Zinc melts at about 787F and hot dip galvanizing baths are around 850F.
Aluminum melts at 1200F, though I am sure that if the rivets are heat treated
it's possible they would lose some strength properties at galvanizing
I don't know about the HBX, but most Rohn tower sections aren't so expensive
that regalvanizing, IMO, makes much economic sense even if you value your time
at nothing. I certainly wouldn't hot dip anything that's assembled with
fasteners (no matter what the material) without removing them first and
replacing them after.
Put another way, if the structure pieces are so badly worn as to require
regalvanizing, should't they be replaced?
