With enough hacking, Dolphin could support normal mapping on games which never used it (by adding the relevant information to shaders at runtime), but tessellation would be harder, and maybe impossible without reprogramming each game's engine to support it.
As for the 3D printing, there is a plan to enable the dumping and loading of meshes at some point, so these could then be opened in blender/Solidworks etc to be sent to a 3D printer. Also, when custom meshes can be loaded, tessellation becomes less important.
Everything else you've suggested would require basically the whole of each game to be rewritten, and by that point it would be easier to make an unofficial PC port than to run a modified game dump in Dolphin. That's hundreds of hours of work for a team of programmers for each game.
