Good stuff....makes me scared to see just how bad the collision meshes around weapons and people are. People always complain about "ghost reach" and now im really scared! 
Yeah I'd like to see the player collision mesh. Only thing I'm thinking is maybe the original tree collision meshes were larger than the model on purpose, like to prevent the player sides from visually clipping in to it. But hopefully not cause it'd be really nice to have these improved ones. Especially if they can also free up resources to increase server performance.
