For several years in the 2004-2010 period, QS! was promising a board that would accept a Lionel R2LC radio board and whatever QSI sound board you wanted (Q2, Q2+, QS3000, etc.) so that you could run TMCC and have QSI sounds. They even had a picture of the board on their website. It was never actually a real product and was never for sale.
