I'm not worthy enough to make my own Wall Man inspired artwork, but I'm still a huge fan.
They should just abandon the PD franchise and rebadge it with Wall Man. It'd sell like hotcakes. With all the time spent waiting for action, pondering the next wall-based pose, and linking up stylish moves while hiding from the action, I'd see the game lasting a good 50+ hours in single player.
And multiplayer could be all about 'Wall-Offs' - think the rap battles of 8 Mile, only cooler. I'd show off my best wall pose, and you'd pull off your best wall pose. Witty remarks would be thrown around about various players' mothers, and I'd say how "phat" I am. Then you'd have the opportunity to pull a gun on me and go for the fatality. I'd have a certain amount of time to reach the safety of the wall before you shoot me in my posing leg, thus ruining all hope of me posing my way to victory. If you are successful, then you win the round. If I reach the safety of the wall, we go to the next round, swapping the roles of "shooter" and "coward" until someone wins.
Various team games such as Capture the Wall and Pose Tag would also be amusing for all involved. It'd be like Hollywood Hogan's Fingerpoint of Doom, rendering the target in suspended animation until a team mate rushes to save you from a fate worse than death ... NOT BEING ABLE TO WALL POSE!
I heard that a secret Wall Pose DDR mode would be included if the time-frame permits. But that's unlikely considering the Wall Controller for Xbox360 is still under heavy development - they're having problems making the wall poses emulated properly in the game. Much like the Eyetoy, you'd look like an idiot when you play it because only the hardcore gamers understand how the best wall men can achieve victory without violence.
