So I just hit max rank with both Red Veil and Steel Meridian. I switched between both of them so I'm hated with everyone else. I don't have any actual loyalty, beyond the rewards I've yet to receive from the two factions. I didn't realize I could have chosen either the left three or the right 3, otherwise I might have just done that. I've read strategies on how to max rank with 4 syndicates, but I haven't seen any advice for what to do in my particular situation.

This is for anybody with more understanding of the syndicate system than I have, where should I go from here in order to max rank with 2 more factions for a total of 4?
