Last resort is sawing off the pedal spindle, then carefully removing the remainder with a belt sander. Once it's almost gone, it'll be loose enough to remove. You do need a pedal with an Allen hole on the inside of the spindle... I had to do that once on a bike that came to me with pedal stuck. Neither force nor heat would budge it, and I applied plenty of both!
I haven't tried drilling out the spindle, but that should work, too.
