Christians, if Catholics and most Protestants reunited, what would you do after that?

I'm Catholic, and am not interested in "converting" Protestants. They're already my brothers and sisters in Christ. As for non-Christians, they have the freedom to believe what they wish. I would hope that Catholics and Protestants could unite to relieve some of the world's suffering. The Mennonites, Lutherans, Episcopalians and many others have amazing charitable programs; combined with Catholic charities, we could really make a difference.
