Tatara and Arata's full body kakuja are the closest things to a superhero-like suit. [] []

For the cape, there's that robe that surrounds Eto's Kakuja:

I doubt she carries a giant robe with her.

As Eto once stated, a ghoul's kagune shape depends on the user's creativity and intelligence, so I believe it is definitely possible, though, I don't think there's much variety in kagune colors.
