It shouldn't be that hard to make an app that can do something like the Me Tile used to do. Maybe create a simple app in Windows App Studio that can let you add your photo and have it be an animated tile. The Tile Me! app in the store does this part of it. Then the new Me tile when clicked can bring up a page that has the social network links that will open an installed app like facebook or twitter. It would be nice if it also allowed for viewing your news feed as well.
