Disabling sages?

[Chazar]

I have no idea about modding, but is it difficult to make a mod that disables independent sages et al?

The pseudo-standard MP setting "Magic Sites 50" shifts the game balance towards magic nations and summons, and I think that the main reason for magic sites 50 is an increased chance for sages for everyone (besides weakening blood-nations and clam hoarders, which I still have not experienced as problematic on small maps). So I would like to disable those mighty researchers to ensure a fair research for everyone and play a game with normal research, but magic sites 40 or even less...
