I'm not sure if the later Super Beetle convertibles had a curved windshield or not. There were a few years of early Supers (71-73?) that had a flat windshield, even on the sedans. I think the "fishbowl" type came out in 74, but I'm not sure if it carried over to the cabrio.
The Beetle top is a complex mechanism---the top itself is several layers thick, with an outer waterproof covering, a headliner, and a layer of stuffing in between. It has a glass rear window, and some models may have even had a dome light. Not at all a simple thing, like the average British or Italian sports car. It might well look good down though, with the folded stack behind the back seat, and even better up, as it is designed for flat side glass.
You are correct that it is about the right dimensions to install on a 122. So, also, is that of the Saab convertible, which I think is a simple single-layer type. 80s Mustang and Cavalier also come to mind as possibilities.
If one were serious about this project, it would be a good idea to do a lot of careful measuring before deciding what top to use. You would probably want a complete (body-wise, at least) donor car, as you would need to cut off the edge of the top opening around the back and sides, frame mounting points, windshield header etc., and weld them onto the 122.
