Interesting project, and I'd love to see the result if/when you come to do it.
I don't have a TI, but if it's anything like my Indigo it should be modular. The keybed is one module (very easily removed by unscrewing certain screws on the underside of the chassis), the cheeks are separate (again accessible from underneath, from the chassis, and also via a couple of screws at the rear), the fascia (including all the rear jack sockets) is another module, and all these modules are held into place by the chassis via a good few screws on the underside.
