I broke out my old Hudson and Allen Alamo that I painted up years ago and had a Alamo game. I used 15mm Blue Moon Mexicans and Texans. They are based one to a stand so, I applied some basic home rules and played basically as if it was a 25mm game. The 25mm Alamo works good with the 15mm, but slightly out of scale, but not too bad. I plan on upgrading to 25mm Alamo figures in the future.
