That's.. actually not a bad idea. Though I would say because she died the powers manifest differently then what usually happens with the HSH. Maybe she becomes attuned to nature, and can communicate with the earth.. something like a shaman or something, she uses her voice to inspire the earth to help her or something similar, it's gotta be based on her voice because I feel that's a powerful aspects of her. Basically she would be something of a mix between tetu and zenzis powers
