I would not say impossible but unlikely. First off there is the matter of lith development to begin with. Development has to be stopped very precisely or the effect will over/under develop. To do this on movie film means some kind of loop that can feed film into a vat of developer at a precise rate and pull it out again at that same rate x feet later without getting tangled, etc to dunk in a stop bath in a continuous fashion (so parts of the film are either on the spool, in the developer or in the stop bath at the same time). And every frame has to get near exact the same time or the exposure will seen to vary on projection. Next that time has to be determined. Its done by red light inspection with prints but with tiny film that's sensitive to red light that doesn't work. Realistically you have to derive the time before processing any of the roll (say with a test strip sliced off beginning of reel). Then there is the final matter of movie film being a reversal process. You'd probably lith the first development and then do the standard process to reverse after that but it would effect the look and require experimentation. Also lith chemistry has been set up for paper so you'd have to experiment to get things right for film. There are reasons people lith prints rather than camera film. The biggest is if things go wrong you don't destroy the negative. Anyhow if I were doing this I'd find a film stock that is also spooled to 35mm still cartridges by someone and try to get things working on that before I'd try to rig something up that could process 100 ft of movie film.
