I just PM'ed him...Thanks for the suggestion. I found a 10/22 with a Tactical Solution UNTHREADED Barrel that would be perfect for this project. I am just doubtful that they'll be able to thread it because they're aluminum....
Never know until you ask though!

Thanks for the lead!
Shouldn't be any issue threading aluminum. You'll definitely want a thread protector, though. And you'll want to be very careful tightening the can to the barrel.
