I'd like to advocate the Plicowatt design. Unlike the Protowatt design, Plicowatt doesn't look like a smaller version of Krilowatt. It's important for evolution to make some change in the appearance of the pokemon.
In this way, Attowatt also works. But I prefer Plicowatt over Attowat because Plicowatt seems to fit a little better.
