Oshigiri's jealousy is probably the critical concern, Maiko says, and you say as much to Konno.
Is this supposed to be
Tsurumi's jealousy, or is there something we've missed about the dynamics around Ikue and Honoka?
Edit: nope, just me missing details while surveying character stuff.
Oshigiri is disliked by others because she dislikes them and only mostly hides that fact. Her distaste for her teammates comes from either feeling they're dragging Furuhata down (Tsurumi, Chizuka), untrustworthy (Konno, Tamazaki) or being jealous of how much attention Furuhata gives them (Chizuka again, Miyu).
This means more vote edits incoming, since that's a very solid route to influencing Honoka.
We might mention these during our talk but I think pointing them out specifically is good too. I'd like to try to address everyone, and the only person we seem to be missing is Tsurumi, though Konno already sort of addressed her by saying she'd be better off with Ikue and Honoka.
I didn't get the impression that that was for Tsurumi's benefit, but more because Tsurumi's psych issues are hurting Chizuka. That said:
[x] You know what? You can work with this. Your usual technique involves brainstorming until people run out of holes to poke in your ideas. With Konno's power explaining why your ideas are terrible you'll be unstoppable! This plan has no flaws.
[x] Spend a bit of effort getting Konno on board with Empress Yui-chan's magical empire of love and justice, take advantage of that ambitious self-interest.
-[x] Briefly explain your rules which you should really write down at some point.
-[x] Point out that a normal-size slice of a bigger happy teamwork pie is easier and better than a big slice of a tiny self-defeating sadness pie.
-[x] Briefly explain how feudalism is dumb and how your crack team of bureaucrats and analysts will let you (speaking of pie...) eat the status quo for lunch.
-[x] Point out how useful Konno's power would be on said crack team of analysts.
[x] Basic proposal:
-[x] You're actually looking for more magical girls right now, not less. Absent compelling contraindications you'd prefer to recruit Honoka's entire team.
-[x] Break the team down to remove internal stresses and distribute them through different parts of Nagamioka. Set them up with groups that'll either teach them to play nice or help them with their problems.
-[x] Your guesses: Ikue is unpleasant but will do whatever Honoka does. Honoka just wants everyone to be happy. Tamazaki can be convinced that you're the winning team. Konno has chronic backstabbing disorder but can be bribed with responsibility and recognition. Everyone else will just be happy to have survived Tokyo.
[x] Specific issues:
-[x] If people do move to Nagamioka, will anyone have real trouble following the rules?
-[x] Would Konno be able to convince Honoka of this idea herself?
-[x] Is Honoka aware of how jealous Ikue gets? If no, how useful would it be to make that clearer to her?
-[x] If convincing Honoka directly is problematic, would it be easier to convince Ikue and let her convince Honoka?
-[x] How problematic are Tamazaki's enemies?
-[x] Just how obnoxious are Tamazaki and Ikue? How hard would it be to place them with teams that'd change them instead of being changed?
-[x] Check your guesses about how to break the team down. [Honoka, Ikue] -> A group that can deal with Ikue, [Tsurumi] -> Himari's group for power synergy + friends, [Tamazaki] -> A group that can deal with her, [Konno, Chizuka, Miyu] -> New team near HQ?
