Ford "N" series rims will bolt to the centers, as 1 of the 4 rims that came with mine was a original ford rim (and it was on a center)

you could also patch your rim, depending on how bad it is. Mine had a hole 2-3" wide and about 12" long near the valve stem hole. I took a piece of sheet metal, heated and pounded it the best I could and used sheet metal screws to fasten it. I then welded it in places. My intent was to weld it al the was around, then remove the screws and use body filler to fill in the area and make it look like new. (I'm not sure how wide this rim was, but if it is a 12", I'd concider getting rid of it if you are interested in it)

I have also saw done where you can cut out sections of 2 or 3 bad rims and make a good one, but I am not that skilled of a welder.

my wc uses wedge blocks that seat against 6 humps or bumps on the rim, not the loops like in your cut and paste. my bolt center is 24 3/4 inches so i don't think i could even get with the loop rim. if both rims were bad, i'd just make some centers out of 1/4 or so and bolt them to the 6 loop rims that you have shown. but with one good rim, well darn if you do and will not roll if you don't.

Thanks for the effort. i just keep thinking there's got to be a 12", 6 hump rim out there somewhere or someone thats solved this problem
