1/ and 2/ are of course good objections; I wasn't aware of the cost of a scan (but this kind of experiment could be done by the organizers, saving on trip costs).

But I don't think step 3 is strictly necessary. The main point would be to improve software unrolling, using information from the structure of the roll. So it may be enough to simply put printer's mark at regular intervals, with references.

I see what you mean, before I had assumed you meant an exact replica. If you "just" want to write reference marks to help the segmentation models, then you don't need a papyrologist. It's still something that only the organizers could do, since I don't see a volunteer team being able to afford the expenses. I don't know if the reason they haven't done it until now it's simply that they're a small outfit that has to juggle different priorities, or if they have judged it not worth it technically!
