Hey mods! Potential apper here, with a small question regarding the first echo!

My character here has tentacles, and I was hoping for clarification on whether or not it would be okay for her first echo to be the memory of having tentacles. Like uh...not the reappearance of the actual limbs themselves, just the memory of them having been there. Ideally I'd like to play around with Maya having (purely psychological) "phantom tentacle" feelings, and I just wanted to check that if that would be acceptable or not.
