Unless something has changed, I heard that NCE is very good about answering these types of questions if you contact them.
I use the Lionel PH180 bricks with my MTH DCS system. They are rock solid and a great value. If they work here for you with DCC, I would think they'd perform great.
I am not sure how to get the DCC signal out of each AC brick though? I would think the boosters do it internally?
Unless you can have multiple power supplies on the base station?
