Painting options?

The hols have begun and I have had a busy day in the garden etc. My thoughts are turning to my 30 interwar Swedes on the painting table - actually an upturned biscuit lid! Some time ago in another blog I explored interwar Tradgardland -http://interbellumimaginations.blogspot.co.uk/search/label/Tradgardland
and some troop ideas etc. I am now thinking of painting the Swedes as the aforementioned Tradgardlanders.They will engage in a Very Ducal Civil War with a variety of Duchy based factions and beyond. BUT and it is a big BUT,is this just a vbcw with different uniforms? Should I paint the Swedes as Swedes or my Lutherans for the League idea.What do you think?
