Lots of crazy Russian, Baltic and other small air force subjects exist for the 17. Check out the Russian Aviation Colors books, which are now 3/4 translated into English (volumes 1 to 3 out of 4). There are enough weird and fascinating profiles in that set and the Flying Machines Press book on The Imperial Russian Air Service to create five or ten decal sheets in 1/32, and that doesn't even need to include those red stars for someone with a Cold War phobia of those pesky things.
The French had some interesting decoration too, but you'd need to go to a Nieuport 11 to put the "boxing bunny rabbits" insignia worn by a Bulgarian machine. You actually can't make up stuff as strange as what really happened, but it is fun to try.
edit: or was it Romanian bunny rabbits? can't recall right now, both look pretty interesting.
