I eventually settled on Summoner using the Sorcerer archtype. I figured since the companion was something I wanted so much, I'd focus on it. I think the last player is thinking bard, but I'm not sure yet.
I was talking with my DM, and I said I wanted to go Dragon Eidolon but with the primal spell list. He didn't seem to think there was a problem because dragons are with every tradition now in the remaster, is there any problems with doing that I can't forsee?
