If he does I think it could be interesting to see him actually fight Loki. With Luffy and Loki going after Imu Gunko together there’s a chance even they might need to call for backup. Shamrock maybe being amongst them. Plus with both having devil fruit weapons and maybe both having fruits of their own the matchup sounds interesting
Plus he has no obligation to fight weaker opponents than Zoro or Sanji because they don’t effect him
As weird as it sounds Imu Gunko really could be Luffy’s main fight of the arc. It giving him to basically fight an extremely nerfed version of Imu before he fights the real one
Gunko being strangely unique when it comes down to her powers and relationship with Imu. Seemingly being the only god knight to be able to summon the rest whenever she wants, not age, and just spend the most time with him. All this while seemingly not even being top 3 in strength in the god knights and a lower contract than the gorosei
Maybe unlike with the gorosei Imu can’t summon his true power or body. Meaning Luffy actually has a shot at beating him while in that state
