Maybe not extreme, but it was clever, very clever...

I've rebuilt PCBs using epoxy to make flat surfaces and then used old
PCB repair trace kit to make replacement traces. Making a small PCB from
some good photos is certainly a good idea!

Extreme might be if you had to do this on the ISS (International Space
Station) for the life support logic PCB.

Or even Apollo 13. Crew saved by making a life-support CO2 filter from
plastic bag, a manual cover and gaffer tape, now that was extreme repair

True, but we were talking about extreme PCB repair. Loved the movie, and
remember the incident (I'm a wee bit north of 60 you might say).
