Default Possible to port G Pro 2 features such as Knock Code, EIS and etc to G2?

Since the hardware specs between the G Pro 2 and the G2 are mostly the same is it possible to port some of the features present in the G Pro 2, such as Knock Code, EIS (which is a software imagine stabilization that's present on top of OIS) and other features?

It appears that some features such as 4K and up to 120FPS recording has already been ported to the G2 so the other features wouldn't be that much of a stretch no?
