Nah, cut it off.  Moto-tools are god's mechanical gift to humanity.

They make a cutoff attachment that can hold light, heavy, and super duty
cutoff disk wheels.  Don't skimp on which duty rating you pick...too light
a disk will disintegrate unless used very carefully, and if the metal is
too hard, the disc will simply go poof(or crack; eye protection is a
-MUST- with any griding tool.)

The great thing about the mototool is that it can be used to grind very
finely, so you could, if you wanted, slot the bolt on both sides, and hit
it with a hammer or something, once you started to hit the threads on the
bolt(at which point, there wouldn't be much bolt left.)

Several slots might give you more of a purchase on the bolt with say, vise

The heavy vibration and heat from the cutting disc might loosen
up the bolt a little...
