Looks like Persona 5 might be getting the FES/Golden treatment soon.

Would romancing Akechi affect the plot or no (not that it usually does for other characters)?

For me to some extent the opposite although more an issue for P6 than a director's cut for P5 because I don't want them to take away stuff. I'd like there to be characters of both genders for whom romancing is not an option. It's just a bit too much to me that you can romance every female social link. At least in P3 and P4 you couldn't romance every female character, even if it was just kids and elderly woman that you couldn't....wait I guess you can't romance Makoto's sister. That's something. Sure, it's kind of funny that you can romance the teacher and doctor, but also messed up.
