Long Barrel mod for SMGs?

[MasamuneZenith]

So I was wondering if someone could do a long barrel and long ported barrel attachment for the SMG. The real Thompson M1A1 did have such a barrel and would be a nice inclusion to it's modifications. Would probably do the usual stat changes for the weapon with long barrels, increased range and possibly damage, lower hip fire accuracy and such.

 

Example of tommy guns with the long barrel:
