Would there be any point to have a device similar to a b-bender, that could somehow have individual control of all strings? There are some devices that bend up to 3 strings, but would there be any need to use all 6?
Some would say just use a pedal steel guitar, but I think there would be enough of a difference in the sound and possibilities of the two (not just the fact that they are both played in a different way).

Would anyone have any desire to play something like that, and what kind of things would you play on it (chords, lead, etc)?

I guess there is no practical point to thinking about this stuff, its just kind of interesting.

Sorry, I was pretty unclear.
Something that gives you control of the pitch of each string independantly, kind of like a b- bender (which is just for the b string).
Heres a video of one in action:

One on every string would be very excessive, but im sure it would sound cool. It would need to be controlled by pedals or something.
