I would send a photo of the rim and the bad nipple hole to your chrome plater, and ask if they can fix the nipple hole.
Contrary to popular belief, there are hundreds of shops that do chrome plating. Most of them only do things like the racks in your kitchen oven - for the manufacturer - they do thousands at a time, and they're nice new steel that requires no preparation and minimum finishing.
There are few shops that do motorcycle and antique car parts. These kinds of parts are usually crappy to begin with, require a lot of preparation work, and a lot of finishing work. The actual plating part is the smallest part of the job - the prep and finish are individually-done manual labor. Good shops fix things as a matter of course.
Your rims that have rust and pitting, and have been bashed against curbs will come out looking like new - if you pay the price a good shop charges. It won't be cheap, but all that individual manual labor costs money.
After stripping the rust, old plating, etc. off, they often need to weld and grind cracks and larger imperfections. Then they copper plate the part. The copper will fill pits, and is easy to sand to a smooth finish. Lots of manual labor getting the part smooth, especially wheels. Then they nickel plate the part. Nickel sticks to copper good, and chrome sticks to nickel good. Then they do the chrome. Afterwards, there's a lot of manual labor buffing the part to a bright mirror finish.
So email your photos to someone like New England Chrome Plating, and ask if they can fix the spoke hole. Places like them have done a whole lot of motorcycle wheels over the years. If they say they can do it, it's probably a good choice. If they say no, there's probably a reason. And they'll give you an estimate on the work.

BTW, nickel is a good in-between plating for many things. You can NOT cadmium plate stainless steel. But you can nickel plate stainless steel (using a "Wood's Nickel Strike"), and then cadmium plate the nickel surface.
