I agree with Rob. Look at the wording of 250.122(B). The "increased in size" sentence was recently revised to clarify that it means "increased from a size that would have been sufficient for the required ampacity." In your case, a 3/0 would have had sufficient ampacity for a 200 amp load, and you used a larger wire than that.
125 amp bus in a panel is pretty common as the "low end" that is produced. If you want to supply with only say a 60 amp feeder circuit, chances are you will still only be able to find a panel with 100 or 125 amp bus. ...
