Is it possible to replace the standard "switching block remote control" as Citroen so eloquently put it with the one from a C5 with flappy paddles?

These are the items in question.. It looks as if the paddles themselves are separate to the base unit so maybe the entire unit doesn't need replacing?
Of course this all depends on how the signal to shift gear is sent to the gearbox. From my investigations with Diagbox it seems like all the normal gear stick does (when in manual mode) is send a CAN command so presumably these paddles also send the same command?

I'm tempted to buy a pair here and see if they work out of the box..... what could possibly go wrong
