tuners for headless guitar

in the comments of the previous post, I had interesting feedback from Alex of Aluminium T-beam Guitar blog, who is particularly interested in headless guitars and proposed in reaction to my 'open bodies' a ingenious way to put regular tuners behind the bridge :

to complete Alex's idea I would put the supporting tuners plate inside the body and not on it, and protect it with a bridge cover, like this:

and to develop the 'open body' idea, this is a more precise sketch of an open-semi-hollow body with neck-trough that should be big enough to allow big holes and easy access to the tuners, and have the proper structural strength.
