Someone mentioned using a similar scaled esign to Nite Owl's suit from Watchmen for Cap's as a semi replacement for the feather like scales so I took a stab at it. Colours are a tiny bit off in cases, but it was just to see how it looked.
I assumed the top half would be the only part to change completely as he's often drawn with pants similar to the ones used in TFA.
