I am learning about the modes, relative scales, and the circle of fifths. I am interested in adding key changes to my playing.

I understand that if you're playing in, say C major, the easiest key changes to make are to the immediate right and left on the circle of fifths. That would be, to G major (a more common, "rising" key change) or to F major (a jazzier, "falling" key change). I also understand the gist of mode relativity. That is, C major is equivalent in note makeup to E Phyrgian etc. 

So say I'm in E Phrygian and I'm looking to change keys. Could I use the following logic to select my next key?

1) E Phrygian = C Major

2) G Major is a nice key to change to from C Major

3) G Major is relative to E Aeolian and A Dorian

4) Therefore, I could easily change keys to E Aeolian or A Dorian

I am grateful for your help. I appreciate any resources for learning more about these topics, but I am especially curious to hear if this sort of logic checks out. For reference, here is that circle I have been talking about:
