I don't know if the standard throttle bodies would work with the Touring. The stepper motors and other sensors may not plug into the wiring harness. MAP and TPS sensors may be different, injectors may be different and if I remember correctly my dealer said the throttle bodies for the standard Rocket are $1800, injectors are $150 a piece, so you'd be into it $2 to $3K before it's all said and done unless you could find salvage parts. Then you have the whole issue of figuring out fueling and ignition maps.
GPMAZ someone has to take one for the team, order up the parts, take some pics of the swap to post and let us know if it works or not.
