I guess you are not into the "probably comic" adventure part of that idea. It looks very Grimm.Although a Grimm Pyrrha construct could end up being humorous after it appears, scares/traumatizes people, and then waves & says "Hello again!" in a bright tone. I am not really into the idea of a Grimm Pyrrha, although it might be very effective in the right situation! (Hey I just watched Devilman Crybaby in two marathon sessions, so there is room for grimdark stuff when done right.)
