Ok, so you may remember this picture of progress towards my failed masterkey project

Sorry for 5yo blur as F**K, but it's given me an idea. I'm going to attempt to do a tank reinforcement and tank expansion on a BBUMB at the same time. I'll drill holes into the actual tank to allow airflow, then glue a 1.5"x.5" threaded bushing over the front; the .5" section actually fits fairly snugly around the original barrel and valve opening and is threaded for different barrel setups, and the 1.5" part seals against the ridge of the tank as seen in the picture. For the back half, I can again drill some holes for flow, glue some CPVC around the pin, then use a 1.5"x .5" slip bushing with a PVC stub to seal the CPVC and a 1.5" coupler to seal with the front. Using a coupler will give even more support to then tank, and will allow me to space the back bushing away from the tank some if I want to increase the volume more than already. It will also allow me to bolt the rear bushing into the coupler instead of gluing it, meaning I'll be able to remove the bushing in case the string to the pin breaks or there are other issues. Seeing as the front part of the valve on the tank I'll be using has already been cut down(damnit past-me), there's a really good chance I'll end up with the pin misaligning often, especially with a string instead of the trigger pin and lever. I figure this'll end up with somewhat-similar performance to my EPVAT, but with less effort on the seal. It could also be done to a new BBUMB since the shells are nice and spacey. I'd actually really like to shove something like this in a Thunderblast when it comes out for awesome rocket-shooting.
