Bill,
I think my preferences are mostly in line with what you are saying. I'm in a local group that includes 3 railers and 2 railers including some proto 48ers. There is a fair amount of RTR stuff on our layouts so the sweet spot you describe may be more prevalent than you know. I know John Sethian who posted here uses all Atlas track and turnouts. The only reason I did not use Atlas turnouts is because when I designed my layout they were not available. I think that turned out to be a good thing for me anyway.
Switching to 2 rail added a new level of satisfaction to the hobby for me, but I wouldn't worry about getting more people into 0 2 rail. I think the best you can do is enjoy the ride yourself and share your enjoyment with others if you can, including on the internet. If people see what you are doing and like it, they'll come around. But one thing I find appealing about 0 scale is that since there are fewer of us taking on the challenge, I think that makes it a little more special to me.
