If you want to add historical nations though, how markings for nations which actually had air forces - like the Austro-Hungarian Empire, Imperial Germany and the Ottoman Empire?

A-H and Germany would have exactly same markings - first the Iron Cross later switch to Balkenkreutz. WWI Bulgaria too.

Ottoman Turkey had the same markings as the later Turkey. Early on the markings used to be either black or red squares, later they settled on red.

Specifically, I was thinking of early WWI A-H with the early red-white-red markings on the wingtips, and perhaps an A-H medals pack. I know they later switch to German markings.

For Imperial Germany, I was thinking red and blue sides (so you can have fights vs. the Russians with Russians red and Germans blue, and fights on the Western Front with Germany red and the U.S./France/UK blue) with the Balkankreuz and the WWI Eisenkreuz, which had arms which were longer and narrower than the WW2 versions (and, of course, no swastika tail flashes). Add to that the WWI medals, with the Ritterkreuz at the top of the heap. Since I'm dreaming, you might as well add the post-WW2 Luftwaffe to the list - fighting for Blue, but with the modern, smaller, Balkankreuz and a de-Nazified medals pack.

Ottoman Empire markings varied. I was thinking of the early black squares edged in white. The current markings for Turkey are WW2 era - red edged in white.

I'm sure that the Canvas Knights wizards will fix the problem eventually, but no harm in someone else having a try at it.
