I have the same problem. The figures that come with the kit are all saluting or something useless like that. I'm looking at Z scale (1/220) figures from model railroad sources. I think that if the figures are in working positions, the 10% size difference is less likely to be noticed. It worked when I crewed my 1/144 Bismarck with N scale (1/160) figures.
