It can be done with care. It might take an hour or two and four tries...
Broaching by hand is also possible, but I'd recommend against it. If you must, use a small file, and you can't hold it by hand - clamp it and make a sliding block.

Alternative: Make a flexible coupling. You can buy one, one side 5/16" and drill it out, the other side 5/8. Make one by drilling out two seperate pieces, and use a heavy piece of stiff rubber hose to connect the two sides together (use hose clamps, balance the assembly).
