It would cost slightly less than a 2014 model with ABS. Seriously, there are so many things that would need changing, from the special coded wheel bearings, to the ECM, wire harness, etc. that it is cost prohibitive.
From anything I have read and the one person I know that has tried it the TCB system seems to be a pretty good product. For those of you that want to know a little more about it here is a link that explains it quite well.
