I reckon that should work fine, in that pic you posted, the middle diagram is how the pickup switch is wired for the Eric Johnson Signature Strat, he uses a .1uF tone cap instead of the usual .022uF though, I personally can't see why the bottom diagram wouldn't work and if you wire up the selector switch that way then you should have the tone control nearest to the volume control working on both the neck and middle pickup, and the other tone control working on the bridge pickup.
