Summoner advice?

[Munkir]

Any way I can use intelligence instead of charisma for a summoner a archetype or feat something?

I looked up and down at the summoner and haven't found anything but I may be wrong. I hope I'm wrong

Sorry,the only caster I know of that can do that is the Sorceror(with the Sage bloodline).

Nothing official. With good reason too.
