As time is not maybe on your side, a trip to an engineering workshop might be your best bet. If you progress with the Dremel Route an impact(black in colour) slotted screwdriver bit, will stand abuse a lot better than a normal chrome vanadium one. Expect Halfords will sell them. Also there’s a freeze spray I’ve had success in the past with. I know Loctite and Sealey do a freeze, shock and release spray. Another thought would be a mobile welding guy, if you got some 13mm nuts he could weld on for you.
