An A-5 would certainly work.
If you go the Fw 190 route, there's a fantastic book out there (think Kagero prints it...mine's packed away, alas) with something like 20 color profiles of A models up through the A-8, with accompanying markings in 1/72, 1/48 and 1/32 (printed by Catrograf, no less). I find a lot of 190 markings seem to be very similar and boring (gray splinter, gray mottling!), and these were very much unique and awesome. Maybe somebody else knows the book I'm talking about...but definitely worth tracking down.
