This seems to be just fine - 4 types is manageable. The strong 3-suiter is not without its problems over, for example, a 3NT response. It is not always clear whether the hand is strong or weak without good agreements. But without having to devote bids to the strong minor suit hands there is enough space to sort it all out - do you play 4m over 3NT shows this hand, for example? Having said this, I am not entirely sure it is not better to include a Roman 2NT into the 2C structure - there is enough space to do this once you have a strong balanced hand in 2D.
