Unfortunately, that didn’t work out. I tried making one out of a frame exposed 10 minutes before, which ended up having the emulsion and a lot of the white crumbly stuff stuck to the front of the frame. But the film that I exposed about two hours prior ended up splitting in a way that let me remove just the clear front plastic cleanly (to do this, I followed the technique described here: analog.cafe/r/polaroid-emu…)
I happened to have scanned the frame before opening it up and I made another scan with the clear plastic gone, which I then overlayed digitally to compare the results (attached). On the left is the scan with the plastic gone and on the right is the original frame.
Even on a crappy flatbed, I could see that the highlights were a lot clearer, there were obviously no Newton rings, and the dirt and scratches were gone (with the protective plastic). And I am sure the results would yield even better sharpness/resolution on a decent scanner as well.
