I set logo1008 for one of the teams. Load the roster, check logo in game. Load logos_large file in modtool, find this logo there, replace texture with my texture, save, load logo1008.iff file in modtool, replace with the same texture, save. Rename and create tiny, small, medium files from large_logos. Very often GID is different than logoxxx. I think its similar with your way but i wanted you to know how to not make little mistakes. Sry if things are obvious for you
