In any case, any and all photonic radiation (either incoming or outgoing) near an event horizon will be de facto gamma radiation due to the blueshifting near the horizon.
That's not true. Photons are blueshifted when moving towards a source of gravity and redshifted when moving away. Your link about gravitational redshift even confirms this:
You're just reiterating what I said. In the presence of a very strong gravitational field (i.e. near an event horizon), any photons in the vicinity, whatever their wavelength, and whether or not they're incoming or outgoing photons, will be BLUESHIFTED due to the gravity. I grant you, if a photon somehow manages to move sufficiently far out of a gravitational field (as I believe I've already mentioned) then it may well become redshifted and you'd have your microwave or radio wave radiation. The overwhelming majority of Hawking radiation photons will be emitted somewhat close to the black hole's horizon, their likelihood of further escape from the black hole's gravity is actually somewhat negligible; granted, also, any photons we OBSERVE coming from a black hole are also; granted, more than likely; going to have been REDSHIFTED at some point.
