If you're going to make roles out of thin air, I might as well too:
Lava Golem/Forest Spirit : Can "grow" their vote for .5 each turn if they sacrifice .5 of their vote for the current turn. (For example a Lava's Golem's current votepower is 1.5. He uses the ability which makes his vote count as 1.0 this turn and 2.0 the next turn.)
Pest : Nullifies the vote of target player, regardless of how much the voted counted for.
