Quick question, I'm probably not going to do it but can we still feasibly make a melee guy who dual wields LMGs?

How would that even work?

That's impractical. But possible. Funny enough you'll need to be a high level fighter who has feats that allow him to both: 

Use Two-handed Weapons with one hand 

Use Two-handed Rifles

Which are feats you can get when you level up. However the highest level your characters may start at is level 3, and not everyone is going to be a level 3.
