Re:
My first thought is stop!
Don't use a wrench, use a socket, a good six point, non-chamfer socket.
This gives you 6 points of contact versus 2 with a wrench.
Soak it with liquid wrench, PB blaster or one of those for an hour or so before trying that.
I am sure others will chime in, but a wrench on that is a recipe to round all the corners off. Use a good socket.

Re:
Sounds good so far, I thought you were going all out wrench.
I say non-chamfer socket, as many have a bevel from the very edge to the flats, so if the edge is 2mm tall, and you have 1mm of chamfer on the socket, you can see how that sucks.
You can 'make' a socket non-chamfer by grinding it down flat on a belt sander.
With tools out of the way, you can tap on the edges a bit - not sure if that will help much.
Heat I don't think so. By the time you get really warm, you will start deforming the air seal, and those are like unicorn teeth, so I wouldn't risk it, unless it gets real.

Re:
take a small, sharpish punch and a small(ish) hammer, set the punch onto the corner of one of the rounded 'square' wrench edges, at about a 45 degree angle to cap rotation direction; and gently tap the punch with the hammer until the top cap loosens (this will damage or destroy the cap, but it sounds as though it doesn't really matter any longer, anyway).

Have you released the pinch bolts?
I've had several caps (more than i'd care to think about) that despite not technically needing the pinch bolts loosening, according to the manual, massively benefit from just taking a turn off them. Especially if they've been moved (or overtightened) already.............
