High Allan !!
There could be a solution for your problem
Well, what kind of camera do you use?
Just asking, because I had (actually still have) the same problem with some unperforated color Film. Usually I take pictures with my beloved Minolta 500 (maxxum 500 in the US), but ordered now an newer Minolta Xi7 for some experiments. These full electronic cameras with integrated winder do not necessary need the sprocket holes for film transport; film is mainly transported by the take up spool on the right side. As easy as the gearwheel (for the sprocket holes) runs, I suppose it does drive only a opt. coupler for measuring the film advance electronically.
In this case the cogs of the gearwheel could be grinded down and be replaced by a thin rubber layer / O-ring to give adequate contact.
I have no Idea how transferable this is for other cameras, for the Minolta Xi series it will work for sure
Im still hesitating, because I do have only two rolls of unperforated films, but for 10 Rolls it would be worth the trouble.

Stefan
