Well, electric-fire pikachu looks pretty cool, and some of the fan art is sweet, but I can't get over that thing's stoned look.
At any rate, a branch evolution for pikachu is definitely something I'd want to see. It could have the chance to make pikachu actually usable, perhaps physical instead of special, similar to gallade. Iirc gallade/gardevoir is the only family to have 4 different pokemon in the same "line".
