That seems pretty legit, pretty legit. You also have to remember that doing the 6A IAD stuff moves you a fair distance... Which may be moving you in position to do a combo with Ada, which means more easy damage and ending the combo with very convenient knockdown or a tech trap into more easy damage.
On a related note, here's something pretty sketchy yet awesome. If the opponent isn't exactly right next to the ground when you hit them with a CH 6A, and they're coming in at a high angle over Carl (that is to say, you're hitting with the part of 6A that is relatively over Carl, and not all the way to the side), you can do cancel the 6A to 236A and cross behind the opponent, and do 2B 2C to launch. This won't come up much, but whenever it will it is quite unambiguous and you should be able to react to the situation accordingly; teleport in Ada during 6A and you have a very easy, pretty good combo. The situation I can see this coming up most in is if you're right in the corner and being rushed down (by specific characters, granted), which is also the situation where it is easily best.
