It's simple, all you need some off-set caps!
Seriously, your hammer may not need bending. Looking at your third pic, the hammer doesn't look to be installed even close to having it's mounting screw perpendicular to the bore! It seems your cocker is cock-eyed -- is the screw bent, misaligned, or what? With the hammer screw seemingly out of square, I can imagine all sorts of nasty consequences. How's the sear alignment? I'd address this assembly problem before firing-up the forge.
