Yep, had the idea of using those LED heads from the flashlights Harbor Freight always has on sale. They fit in the hole real nice all you would have to do is machine an adaptor to fit them in the bedroll, which is appx. 1 9/16" and the head of the light is just under 1 3/16". I had the voltage figured out at one time, the array is powered by 4 1/2v so you needed to slip a dropping resistor in to bring down the 6v or 12v supply to 4 1/2v but that's no big thing.
I wasn't going to do it to mine because I want mine as stock as I can keep it. It looked like a good idea and also a rather inexpensive one if you had access to a lathe to make the adaptor.
Not sure what you would use for a lens though, the LED's emit light in a single wavelength where an incandescing bulb gives off light in all wavelengths. So colored plastic lenses with white LED’s behind them may give off some odd colors. That said, I did spray some clear plastic with some acrylic red paint and the lens looked pretty red to me. You might have to do a little experimenting with it
