Not as easy as you would think. The interior would have to be fitted for the exterior of the specific weapon. Also, that M-11 is a class 3 weapon, so you're talking a bunch of hassles right there. You would probably have an easier time putting aluminium shrouds on a real Thompson. You can legally get semi auto versions of those, albeit not exactly cheaply.
I agree with Greg this is not a project they are doing to make a production of. This is to show off what they can do.
