Yea you could do it but will possibly waste a pic or two. In A dark room or changing bag, load the film into a Packfilm camera to hold it steady, but dont shut the back. Very carefully separate the first white tab from the second, then gently pull it, you should end up with the tab pulling out the pos and neg, joined at one end, but not used as it is dark (so no exposure) and pods ok as not through the rollers. Hard to explain but if you have ever had a packfilm shot get stuck and not come through the rollers, shd had to open the back to remove it, you'll know what I mean! Sounds interesting, good luck!
