They should just change the gas system. Replace the gas tube with a gas piston. That will keep it a lot cleaner and more reliable.
If they did that they'd end up with Daewoo K2. About 95% of the lower receiver group is interchangeable with the M-16/AR-15 and uses a AK-47 style gas system and an FN-FAL style folding buttstock. In all, a very reliable and robust weapon.
