The direction of the development of Lionel's AF line toward a scale friendly stance is very encouraging and exciting. For myself, a more scale influence is a positive thing and the possibility of offering a DCC add on is very appealing.
Two questions come to mind:
1. As the DCC board would be an add on to the Legacy board (as I understand your post), would the primary power source still be AC? If so, this would be a distraction for me.
2. Would it be possible to offer the DCC plug in to a Legacy less, DC powered, locomotive? This would be the most attractive alternative to me.
All things considered, S scale much better off with the current direction Lionel is taking in the S market than without it. I applaud your efforts!

1) The power would be DC or DCC, *not* AC.
2) yes we could consider a DCC socket. I am not sure the best path right now, a DCC plug, or DCC support from Lionel as delivered. The DCC path from Lionel would have many advantages; working Smoke, Railsounds, IR Track emitter, Legacy Quilling horn, ect. Downside would be a Lionel designed DCC decoder, which is a relatively unknown product. However, I have designed DCC decoders many years ago, and followed the NMRA spec, so one would believe we would be off to a good start...
