I've seen a "dummy" 12g CO2 canister, that allowed you to plug in an external HPA source and use it via that way, haven't seen any 8G ones though.

I'm curious if it would be feasible to drill and tap an adapter into a spent canister and gas it up that way? A little DIY project.
Nothing crazy intense in terms of PSI, say ~120-130 at most.
I hear they are apparently full at ~800-something PSI from the factory.
Thoughts?
Thanks in advanced.
