Look at the 2006 Arctic Cat F series snowmobiles.
They have a system sort of like what you are describing that could possibly be adaptable to a bike.
Sort of like the adjustable comfort stems, but with a quick release.
2005 Polaris IQ RMK's had something similar too, but their system is totally different from what I think could work on a bike.
The Cat method would probably work much better, but will require some fabrication too.
