I think Fenn is right on with his suggestion for modifying that pouch to get the "Fett-aesthetic". If you pop off that little strip and secure it with some velcro or a snap al la ESB that would work.
As for the hose connector, I just drilled a hole in the hose where it goes up into your sleeve, slip a caribeaner hook through the hole, sew an elastic strap up under your double sleeve, and hook the caribeaner hook to the elastic strap. 
Thanks Mi'ix. As always, you're EXTREMELY helpful. I think I'm just going to stick with my Boba belt for now since that's that one I already have.
So this is probably the last major build update for this thread. I got my Manofwar flightsuit in on Wednesday and I gotta say, I was expecting it to be more on the tight and snug side. It is on the arms but otherwise, it's not! (I wouldn't have fit in this thing several months ago)

I went out and bought Rit Dye during my lunch break that same day from Hobby Lobby and got tan and camel colors.

I dye bathed them that night using a 5 gal bucket and mixed it 1:1 of the tan and 1:2 of the camel.

Admittedly, I thought this would turn out lighter but honestly, I'm happy with the way it turned out.

All that's left is weather washing with some black and dark brown spray paint and then brigade app photos.
I'll post them on here first so everyone can comment on any adjustments if needed.
I'm going to try to shoot for next week for my photos. I can't believe I'm THIS close, guys!
