thinking here, always thinking

I have been waiting for the final 45' of the GC's. soon I believe the west side of the war will be comming out with all it's GC's.
I like to save lots of work and let other people do the hard stuff like the Devs are doing.
my question: what would stop me from interchanging the east with the (new) west files at a given point if I wanted to go to the west in a campaign using the already developed files of the future west side of PzC?
say I go to 41' or 42' to a certain point and change over to the west?
same equipment time frame for both(has to be) and same game mechanics I suppose. unless, the new west mechanics is drastically different from 1.05? also this question is a kind of what's in the 1.06 update too
