Not so, as I mentioned in the other poast about it, potara fusion when a kai is involved is different
The kai is the “dominant half” and stays mostly him/herself, with some traits of the other partner
Old kai is not actually old, he fused with an old witch, which made him old but still a man, and when Zamasu fuses with Goku Black in Super, he’s just Zamasu with Goku hair
THEREFORE the fused being of myself and Chronoa would just be Chronoa with some slight me-ish traits
