There are a lot of vape pen batteries that have a voltage adjustment at the bottom. It seems feasible that one could wire this potentiometer to the board and vary the diode current. Anyone ever tried it?

This would not work out. The „constant current“ driver on the laser is designed to keep the current constant, whatever voltage the battery delivers. If it falls below the threshhold, it simply shuts off. If you have a „boost“ driver, the electronics would try to raise the voltage above what the battery supplies. You would only make life harder for the electronics to do the job it is intended for. You cannot regulate beam intensity with it.I was thinking that it might be useful to turn the power down when traveling to avoid any issues with TSA
