Hummmm... that's more effort than I want!
No issues with ducting underneath, just need enough space to pass a few wires 
Here's my prototype... to be honest, starting to thing it's more effort than I need... I can probably get away with only 2 switches, and putting one in the spare slot to the left of the steering and one in the right slot...
On the other hand, a set of aircraft switches could be quite fun to have; even if they just control the lights!
