^ Not to mention it'd depend on how the company handled her. For instance, when KAITO was being upgraded to V3 due to the vast difference in engine quality KAITO "straight" was recorded not as a straight up upgraded voice, but recorded in an attempt to match the voice from the V1 engine. There's also the case with Lily where the new voice sounded so different from the V2 engine they decided to throw in another bank which could replicate that voice.

Whether Teto would keep her original tone or not in a Vocaloid engine would all well depennded on if Twindrill wanted to try to* or not.
