I'm sure that you are on the right track here but I think you need to be careful with UV which is very energetic & may cause damage.t is a long time since we used Infrared and Ultra Violet radiation techniques (as used in forensic and fine art photography) and wondered whether one of these would be suitable to enhance the illegible writing?
I recall that an archeological dig near Hadrian's wall retrieved a number of fine wooden slips with day to to day admin notes (like "here is your fresh underwear"). These were barely legible when recovered but totally black a few hours later. A university copied them with IR & had excellent results.
I'm sorry that I can't recall more detail.
