If you have a top winder type jack, your knuckles are definitely in harm's way.
A sidewinder, not so much.
I haven't seen a drive nut work on a top winder, but I think it is worth the $35 to switch to a side drive.
Your mod to the handle is a great idea, with or without the knuckle problem, in fact I did a similar mod myself. I simply removed the stock handle (one roll pin) and replaced it with a piece of drill rod with a nut welded on as you suggested. I do recommend having a wrench handle to manually operate the jack as a backup.
