Well, sorry for having to be the rationalist here, but something like that is not going to happen. Simple reason: general game/publisher politics. They'll only participate in something that includes donating/raising/refraining from money, if it's officially supported by EA at first. Otherwise, if they just did it randomly when something comes up, next time people would all the more demand it, using the argument "but you did it last time". Which would bring the devs into a situation noone really wants to be.
