The boom will be a big fat shorted turn, so to some extent it will
spoil the choke, but winding coax around the boom on a form should
still work if the diameter of the form is much greater than (say,
more than twice?) the diameter of the boom.

Put it closer to the feedpoint than one-quarter wavelength at your
highest operating frequency, or you may have resonance trouble.
Remember why guy-wire insulators should be closely spaced.
