It would certainly be possible to have Laukhuff, or any number of other builders, construct a pedalboard/keystack for HW that was essentially a "truncated" tracker system with fully mechanical inter-manual coupling, etc.
On the other hand, if I had the $$$$ to do that, I'd probably be in the market for a private jet, or Lamborghini Veneno, or maybe a small island in the Mediterranean instead. Much more useful
