Cow, not really, still would have to buy a 200 amp load center for the back of the house and feed it with probably 3/0 (a bit costly). The huge all-in-one panel/meter on the side would be empty except for an expensive 200 amp feeder breaker.
You'd have the main 200 amp for the buss bar, then another 200 amp feeder breaker.
