1. Senshi using their own youma
Well, the youma/daimon is basically a thing filled with dark energy. I wonder, if Usagi can do the same, filling some thing with the Silver Imperium energy to create a youma of love and justice?..
The exact way to come to this may vary - from Mercury learning the method from her computer, to Luna's awakened memory, to someone just asking why Senshi don't use the same tactics as their enemies.
May lead to many funny moments, since if youma reflect their creator's personality then the ones created by Usagi won't be very bright
2. Genma as a tentacle demon instead of panda
Well, AFAIR, there was another way around, aka «Ranma the Amorous Oversexed Nympho», but this one, too, does have some potential.
I don't think this worth more than a one-sot full of panicked retreat... But it could be very funny - if somebody manages to fully use this idea's potential...
Like, I don't know, Ranma, Xian Pu and entire Amazon village running away in terror, becoming a friends in a need... and so on.
