It would appear that Cu65 is lighter than Ni64+proton by 0.008Da. The reaction if it were possible - would be exothermic.

You're not taking the activation cost into account. Getting the two atoms to fuse will take more energy than it will produce. That's why no fusion reaction with a product heavier than iron can produce net energy.
