Very unlikely. There is simply no info out there. People put LS's into JK's because there are tons of aftermarket companies out there that provide the parts and the programming.
Also, the 5.9 makes less HP than the 3.6L pentastar. Only 50 or so ftlbs more torque. It would cost thousands to install for no huge gain.
