anything can be done, its just finding someone whe can do it. It would be a very major project, but compared to many other projects it is quite minor. people have put 2 engines in 126s, thumping great V8s, so fitting a Daf variomatic would not be that big a job. as for the engine being in the middle of the car, if you had the inginuity to put this in the 126 it would be a minor job to extend the prop shaft out the back of the "box" so the 126 engine remained in the same place as the "manual" car. after all the standard 126 setup is not exactly the norm with the gear box at the front and the engine to the rear with the diff between the 2.
