I really wish we had a head for Wisp that was like this (or something like this).
Just so I could fulfill my witchy wisp desires. But seriously, why has no one done something like this for wisp? It fits the frame's theme fairly well and we've had frames with "hats" before, such a Hydroid, Mesa, Limbo, and many frames that got hoods through tennogen (not that I'm complaining), including Wisp herself.
Of course, if need be I can maybe try to create some of my own artwork for such a design (since I lack the hardware and digital knowledge to try to create a tennogen skin myself).
