That's what I've done. I originally was going to make my own rack but decided the chances of my dodgy welding coming unstuck somewhere in the middle of no-where was too high!
I got a Touratech rack and the 'touratech style' fitting kit from EIBC and they work well together. I agree the butterfly bolts that form the 'quick release' are a bit fiddly but I'm only planning on using them once a day and it only takes a minute.
The Touratech rack seems extremely robust and appears to have been made in such a way as to stiffen and strengthen the whole back end of my XT. It was a bugger to fit though!
The only 'adaptation' I made to the set up was to buy larger outer diameter washers to use with the screws that hold the EIBC fitting kit 'pucks' to the aluminium, spreading the stress over a larger area.
