Have our CANbus gateways converting HS GMLAN protocol into other languages on high speed networks. So getting the info needed from the 09 ECM is easy. Issue then is converting HS LAN down to class 2 data. What's needed is a two wire CANbus to single wire Class 2 converter. Bet an Arduino board guru could do it given the right information.
Other option might be look at factory BCM's. Right off I don't know of any particular GM BCM's that had HS LAN and Class 2 features, but it's possible some split year model did. If so, I know someone who can reprogram the BCM's to do what ya need.
Please let us know what ya find.
