Well, I've done the tablet conversion to a Pismo (Which is essentially the same design) save the touch screen and regular use. The person who made the iBook Tablet used Troll Touch (http://www.trolltouch.com/products.html) And said they were good. Since mine was supposed to be a media station, it's IR controlled, so I didn't need that.

It's very possible. I'm in the midst of writing/finishing my Tablet, and it's coming a long quite nicely. Do you want the screen flip ability? Or would you be satisfied with the touch screen tablet?
