i was able to get the technic vanilla to 1.2.4 by replacing its config,bin, and mod folder with the plain minecraft launchers one, but they share worlds now(i start a world on tecknics vanilla and it appears on the minecraft launcher game and so forth but the mods i put on the technic one dosnt show on the minecraft one so i assume it works) dont know if this helps any, or if their is a better way, whitch their probably is, bu ti hope it does,
