Consider doing a hybrid workflow. The equipment for developing film is quite compact. I keep all of my film development chemicals and equipment stored in a small tupperware under the bathroom sink. You can also buy a lightproof bag, so you don't even need a light tight room to load the film.

The second half of my process is to "scan" my film using a macro lens and my DSLR. It takes about 2 hours to go from exposed film to developed and scanned film. Only about 30 minutes of that time is active, most of it is waiting for the film to dry since I don't have a drying a cabinet.
