Individually scanning the frames on a home consumer film scanner is pretty much impossible, or at least so much work that it wouldn't be a realistic goal.
35mm=24FPSx121minutes=174,240 frames. And you then have to store them all, stitch them together and make sure that every single frame lines up upsolutely perfectly. Not going to happen. Forget months, this would take years.

Soundtrack wouldn't be a concern, this would be purely for picture information (although syncing would also be a time-consuming matter).
