I ran across this company that makes your 10/22 look like a Tommy Gun.

I'm giving serious thought to getting the "Squad Leader" version. I like the fact that it has a horizontal fore grip and that it can take sling mounts, whereas the "Chicago" version would be much harder (if not impossible) to put sling mounts on.
