do you see this as possible?

Not sure about the 8 or 9", but the original negatives for a lot of the disney animations, beginning with Fantasia were shot on standard B&W stock, but as 3 frame sequential. Made for simpler kit, and as it was animation no issues with colour registration when shooting live action.

Of course in those days that would have been nitrate stock, and that can be a little *ahem* temperamental
