let me think

proximity:when they are in direct body contact, they can both use either ability, not very practical, but would make for some interesting combo moves

timing:They spend most of their free time together(every waking moment, basically),  so maybe if one is asleep and the other is awake, the semblances switch until they are both awake?

other:well, i can think of one thing, but I'm specifically giving a middle finger to that particular anime concept with the ectaris twins, so it isn't happening.
