Miniguns and .50 Cal weapons

Hello,
I have'nt been in the hobby for about 15 years, but I was pretty heavyily in to it back in the day. My question is this, I am building a formation of 2 MH-53's doing a Mid-Air refuel off of an MC-130, What I need is the funky nose thats on the Combat Shadow (variation of the C-130) and the Minigun's or .50 cal plus the Ammo cans and link chute. I know this is probably going to be impossible as I will more than likely end up making the ammo cans and ammo chutes. But, any help would be greatly appreciated.
