HIGHLY doubt any 16" rim would fit.
Well, you should doubt it a bit less, as there have been 16" wheels available to clear the Cobra brakes for years. In addition to the options already mentioned that are available today, Steeda used to sell a 16x8" wheel called the Hexcentric that was advertised to clear Cobra brakes. Those are long gone now, but even when Cobra brakes were new to the market you could find 16" wheels to clear them.
