You know, recent update has me thinking:
With how Cordia gives Eiza the option to join a crew with different Caporegimes (Angelo, Caterina, Battista, Amita & Amata. Excludes Wilfred's Division since as Hopes said, Ex-Capos have no crews), I do wonder if our MC (i.e. player) will be given the option to choose which Capo's crew to join in the near future (I mean, both Angelo and Caterina have been wanting him to join their crews since the Straffan mission lol)?
Each Capo's crew giving different stats boost to MC (for instance, joining Angelo's crew gives a defense boost, whereas joining Caterina's crew gives an agility boost in stats).
Come to think of it, if player's MC romanced Luna and relationship points with her is high enough, I'd say put Luna up as a secret unlockable option as well (yes, she's a odd Capo without a crew, but MC can be her first crew member). Bet that's gonna leave pretty much everyone shocked if MC says "Actually, I want to join Luna's crew." when asked by Cordia which Capo's crew he wants to join (with Luna, perhaps Attack boost is most appropriate, since she primarily focuses on offense).
Of course, this would mean branches in terms of content for a bit (which hasn't happened yet for DeLuca), but should it happen, it's gonna be really interesting, I'd imagine.
