If you go through the work to relace the hoops, it would probably be better to bite the bullet and get non-pitted rims and have them stripped/coated by a pro. I have removed chrome with aluminum oxide (120 mesh) at 70 PSI, but it was real work.
Scuffing and painting will work, but if you relace, you are already in for a penny.....
All it takes is one boob at your MC shop to mount your tire and wreck your paintjob, a true powdercoat, if done properly is very durable.
If you don't relace, then go ahead and rattle the thing, but rims (steel) in good/great shape are pretty easy to get around here.
I got a set of CB550 hoops damn near perfect just collecting dust, as does just about everyone on this forum.
