TFC-004 Gear of War Launchers?

So I've had this upgrade for a good long while now and I just opened it tonight. I put Inferno together, messed around with the autoscout and put the Mirage box together. Great, finished right? Wrong, I'm trying to figure out what to do with the launchers and missiles. See I also have the FansProject G3 trailer that came with weapons. So Mirage is using that shoulder cannon. Henkei Red Alert is fine with his chromed weapon as his shoulder cannon. So what should I use these leftovers for?
