This is an interesting premise, but so far you don't seem to be getting
a lot of mileage out of it comedy-wise. I think it would help if you
brought in more characters who don't know about the switch; seeing
people deal with character X as if he/she were character Y, and X having
to keep up the pretense, could lead to some good laughs.
Ranma is certainly lucky that Akane knows about the switch. I can just
imagine what Ukyo would say to her in Ranma's body if she didn't know.
