outside the box idea from a noob

So apparently the joke is that the u in wii u stands for "unsoftmoddable", but here's something I just thought of:

The giant tablet/controller that comes with it.

In theory, you could sync it to a computer, and create a pseudo-emulator that works between the computer and the tablet, so that it thinks it's connecting to a wii, and then send any backup game data directly from your computer to the controller.

Is this possible, or am I going crazy?

For that it sounds like you're talking about a Wii U emulator, which would use a Wii U gamepad. Sure it could be possible but that'd be a lot of work.
