Alright. Hmmmmm. :confused: Lots of info here and so many different ideas. I'm gonna try to sum up all of this into what I think the point you are all getting at is, and using some of my own knowledge too. I am no pro at modes, so this is just a.....how do you say, hypothesis. Here we go...

To simplify things, lets say its in C major.
We have... C Ionian (major scale), D Dorian (minor scale), E Phrygian (minor scale), F Lydian (major scale), G Mixolydian (major scale), A Aeolian (minor scale), and B Locrian (diminished scale).
All of which are using the same notes as the Ionian mode. And from these, to my knowledge, you have chords that will work in the key, being... C Dm Em F G Am and Bdim (correct me if I'm wrong.)

Thats kinda simplified, but I have a question myself. Well, these revolve around the major scale (C major). So, my question is.. How do you change this to revolve around a minor scale? Say, A minor, just because its simple. Is this even possible? (I would hope and assume so)
