I look at this from a different angle, for me the use of 1:120 has always been about making a "railway within the landscape" rather than cramming a lot of track in, whilst keeping the stock and buildings "easily built". That's why N, for me, never worked, it's just too small, especially when you model narrow gauge where the stock is even smaller. 1:120 worked very well on the three layouts I built in TTe and "A Taste of Alber", probably my favourite, shows what can be done in 6x2...
Or this (what you can see is only 8ft long!):
