Ok somehow missed the biggest part of swapping 3 modules.
So another Jayrob inspired build
Your not posting pic's so it's a little hard to understand your idea's but just took a look on Amazon of these Tool AAA's. The 3 different material hosts seem to have a different size tail switch. Some screw in and interchange between the hosts but some don't according to one guys review. Maby buy one with the longer tail switch and work with that, or have a very small extention tube built by someone that will let you run a 1/2 AAA or "what ever is available" or 10440 and use a driver for each module that uses "1" 3.7V source.
