We've stayed at CBR our last two trips, and while I won't agree with you on the bad service - we had very good experience except for all the MB problems with a split stay - the layout is VERY spreadout, making the bus service slow, and the standalone check-in is pretty awful, not so much for the check-in part, but when you have issues during your stay.
I think if they build a DVC in the vicinity, it would basically have to be it's own thing, but take advantage of the infrastructure of the resort. It would almost have to have it's own buses as well, because one of the worst things of staying there is waiting for a bus.
If you look at google maps you can see the check in building (Custom House) is actually very, very close to the back of Epcot. I wonder if they built a DVC resort in the vicinity of Custom House - either next to it, or between Aruba and Barbados - and again give it it's own pool and some additional facilities (store). How to direct link it to Epcot might be trickier, because you have a major route (Beuna Vista Drive) between there and Epcot, but you could come into Epcot through a new waterway between China and Germany.
It would be a LOT of effort though to do all this, so it still makes me suspicious to think it won't ever happen.
I wonder by the time they do Poly, VWL expansion, BC/YC expansion, if they also do a DHS makeover, do they build a DHS resort/DVC? I'm just blue-skying here.
