This is the key. A fuse/breaker protects the wiring and connected components. You can't just increase the breaker/fuse size and call it a day without also being sure that all wiring and components are capable of carrying that full current. You could try to live with the 50A overall limit like parrothd described which might just (barely) work, otherwise you need some bigger cable (there's a lot of factors: I'd use 2 AWG, but 4 AWG is probably OK too). Now, if you are running new cable, I'd probably just leave the existing setup alone unless there was a compelling reason to change it...
