If it were me I would create a 'stretcher' or rack where the film strip gets mounted all flat out. Then a set of long troughs, or tall cylindrical tanks that the stretcher would be immersed in. You could easily control the reexposure by side and light color by placing the rack on a light bar.

Although I'm sure you would have to process in darkness, it could be an assembly line type of affair. Drop in tank1 for time, pull the rack out and on to light bar 1, then on down the line.
