It’s not been updated for a bit but the gallery here on IcyVeins is a great help when trying to find models that might work fill out a set:
Goggles may be tricky as there aren’t that many models and colors available, still got a couple ideas for you:
Gadgetstorm Goggles
Fiery Beholder Eye
Mats for the old engineering goggles might be hard to come by, and the Beholder Eye is a rare drop so that might take a while 
Had a look at some bows and guns for you, thought this looked cool, not sure if the color is a good match though, so check it ingame before you go hunting for it:
Veranus’ Bane
Hopefully give you some ideas, but please come back with an update if you figure something else that fits 
Totally won’t “borrow” it.
