Bigsby Tailpeice And String-through Setup

[LarsXI]

For those with a bigsby tailpeice on a string-through guitar, have you ever tried only stringing some of the strings through the bigsby and the others regular? It could lead to some interesting possibilities, with drone notes and simultaneous flutters.

I've been playing with the idea of modifying a bigsby quite extensively using a thicker rod (where the string mount), a gear ratio and different spring set-ups. In my mind, the bigsby would have a lot of potential if it weren't for the limited range.
