Rewards will include a "rework GG" token. When the community combined have earned enough, he will get a rework. .
On a more seriouse note, it could be fun to make something like 3 events run at the same time, either with very small rewards or with shared number of plays. Each event would then be tied to a character, like GG, Windu and Maul. Completing the events would create points, the event with the most points would be "the winner" and the toon tied to it would get a rework (or perhaps more realistically, get their rework released first).
