I thought of this a while back, too. I really like the idea, but it seems like a more complex thing than I originally thought.
Apart from anything else, you've got the player choosing something in the gameworld - how is that manifest? My thought would be a special one-off temp power that costs X inf at the p2w person.
Also, imagine it's Halloween... trick or treaters are clicking your base door all day. Are you? When you do it, do you get teleported to your supergroup base instead?
