I am not too knowledgeable on BCM wiring but I think that it all depends on which extra features you want to add. I think it would work without a patch harness. This just my opinion and not fact.
Why do you want to upgrade your BCM?

you're going to have problems going from low/mid to lux/high because the biggest difference that I can see is the Anti-Theft. Low/Mid doesn't have it, but lux/high does.

Other differences are easily fitted; electric aerial, variable speed wiper for lux/high and for high only, rear light failure warning (resistance only not canbus), twilight/auto lights (will need a sensor installed/wired)... oh, and high doesn't have an interface for rear wipers on wagons. Guess there were never any high BCM wagons.
