If you roll your own film from bulk, I think you could make it easier on yourself. Just roll a very small number of frames worth (like 3 frames). Why would you want to shoot through 24 or more for a specific effect anyway? Before you use the film, wash it in the paterson, then rig up a dark place like a changing tent (plenty of room if you have a really short segment of film). Maybe put in something really dry with the film (plate of salt, dry sponge?) in the changing tent to absorb moisture, keep the humidity down.
Of course, your ratio of frame to leader goes to hell, but just how many "glow effect" shots do you plan to make anyhow, before it becomes a cliche in your portfolio?
