Replying to Binding/brake question

I have a pair of old look p12s (the pre PX version) mounted on an old pair of public enemies. I'm going to buy a new pair of chronics, and Im planning to put the p12s on my chronics (because Im poor, and I love those bindings). Now the problem is that my public enemies have an 80mm waist that my brakes barely fit over, and the chronics have an 85 mm waist.

So my question is if I buy wide brakes for the px12s, will they fit on my p12s ? And if not, is bending my current brakes possible to make them fit over the 85 mm waist ?

Any help greatly appreciated.
