This >Hipshot Trilogy< rig has A lot of functionality that you weren't looking for, but at least they claim it will install in a Strat without additional routing.

I also found this cool >ABM Headless< setup, but it's uber expensive!

The chrome licensed FR I have was removed from a Washburn A-10 Stage Series Re-issue when I changed it to gold hardware. That would definitely require some serious wood working to install. PM me if you're interested anyway.
