I'd love to try it.

I wonder if a microcotroller could be used to control the electronic throttle body with a few sensor inputs so that it could switch over and have the right throttle opening. It wouldn't need to be super fast, all it would need to do is guess where to put the throttle when it switches over to avoid any jump in power.
Searching, it looks like the arduinos are fast enough to handle throttle body duty. You might need a good 100 datapoints to make a good map though, maybe some way to warn the ECU when it is going to go 13:1 also so that it doesn't go lean.
You may be able to rig up an electromechanical setup that shuts the throttle body somewhat when the engine switches to 13:1 and set up the throttle linkage to take it WOT at part throttle when in 6:1
