Had this very conversation at Warley Model Railway Club 2 weeks ago with the N gauge modellers.
The conclusion was that Z gauge could be used to make a reasonable Welsh narrow gauge layout in British N scale (Ne or N6.5) or could be used to model the Romney, Hythe and Dymchurch Railway or Fairbourne Railway or such like in OO scale. British N scale is bigger than continental N scale.
Checking out the Peco website they do make Z gauge track but you would need Marklin points.
The point about this is that you could use standard off the shelf British N scale or OO scale scenery and buildings and incorporate something into a bigger layout.
Happy modelling

How many times have I visited MRF.....
