If Bachmann and soundtraxx make a DCC sound unit for the HO/OO scale Thomas and friends range, will it keep the same CV selections as the large scale DCC sound unit and add the sounds of the other characters besides engines 1-7, Emily and Spencer?

I don't know if Bachmann Trains will make Duke the Lost Engine in HOn30/OO9 scale since Kato trains has made Duke using their tooling for the Ffestiniog Small England Class. (Except that model was only available in Japan I do believe) I think that Bachmann Trains should make a HOn30/OO9 scale model of Duke from scratch.
