Travel rules it out to be honest. It is not so long ago there were North/South divisions in English lower leagues for this reason. Even now with air travel I can see Plymouth vs Inverness Caledonian Thistle as being a really popular draw especially given the revenue it would drum up. It would help broaden the mind as far as seeing other parts of country but not a lot more.
They do have a potential for great scores along lines of East Fife 4 Forfar 5 though.
