Like I said, either of those would be good for the SMG, but then you're not actually making the actual M7... It loads from the SIDE, and that would take a little bit of work. An AEG build could be your best bet. Spend time on Google and see what advice the dozens of other threads on other forums has to offer.
Here's a guy who built an AEG Kriss Vector. Not an M7 Caseless, but same idea of building a body around another gun. For that side feeding look of the M7 you could get one of those old WWII SMG's that feed from the side. Pretty sure there's a replica floating around. Look for a Sten gun.
