Off the top of my head, sure, you could think of things that way, but I don't see that you get a lot out of that framing.

wut? idempotent is any operator T such that T^2=e the identity. for example ring elements can be idempotent https://en.m.wikipedia.org/wiki/Idempotent_(ring_theory). it's not just characteristic of linear operators.

Idempotence means T^2=T. Are you thinking of involution? https://en.wikipedia.org/wiki/Involution_(mathematics)
