Too late for Edit: If you want to go REALLY CRAZY trying to get in a full or almost full arcane caster in this mini-party but don't want to be the specialized Angel Summoner (although you're going to have to do that a little bit), here's my latest build idea for a Reach Eldritch Knight, although again this would be better in a larger party, due to needing other PCs to synergize with, not having bad status removal until you can summon the right kind of Outsider to do it, and being on the squishy side due to not being able to use significant armor.
Note: You will have to change one thing: Substitute another Magus Arcana for Maneuver Mastery, because Rules As Written, VMC Magus does not give you an effective Magus level to use with it. The build will still work without it, just not as well. I haven't yet figured out what the best substitute is.
