Let's for the moment we think "out of the box". If there is a product
which has the shape of either a 35 mm or 120 film cartridge, and you
can just load it into your old film camera. However, this product acts
like a digital "film", in which it will store images in digital
format, instead of into film, would you buy such a product?

Forget that, simply replace the back of any SLR with one housing a
sensor. Just think of the ease of sensor cleaning! Swing the back
open! The idea of doing this with an Olympus OM-1 was bandied about,
but the logistics would have been daunting.
