Crossovers That Should Not Be 22: Pushing it over the Hedge.

That one was truly outrageous, Rob

We've switched Ami Mizuno (Sailor Moon) with Umi Ryuuzaki (Magic Knight Rayearth).  Let's see what happens next in both continuities...

Is the reason that this should not be is that it would be boring, or is it because Dave Letterman would do an Umi-Ami joke?  Those two stories are close enough in scope and tone that I'd consider them a natural crossover; the only difference would be that when Ami got back home, she'd be fighting Nehelenia in a giant mecha.  Unless the rest of the Senshi manage to Sailor Teleport into Cephiro, which means that saving Emeraude is back on the table.

The should-not-be swap that's obviously here is replacing Esmeraude of the Black Moon Clan with Princess Emeraude of Cephiro.
