i don't think even akainu is gonna bat for the wg in the final war
it's coming
Elbaf mural notwithstanding, you have to wonder how many factions there'll be EOS.
(1) Nika + allied nations on one side---------
vs--------- (2) IMU & WG on the other
but, I see fractures internally, as well:
(3) BB is the third faction coming from the pirate world, both opposing IMU and being completely incompatible with Luffy's ideology;
(4) SWORD comprises the "good guys" within the Marine;
-- (4.5) but I expect Akainu's own faction to rise up as extremist marines who want neither devil-Gorosei nor pirates to dictate the law;
(5) then you have CG which will want to take down IMU & WG, but also replace the Marine, and beat the SHs to the OP treasure;
(6) and the Revs will support Nika and the allied nations, as well as (possibly) SWORD, but will want the WG toppled, Akainu removed, and the CG neutered.
It's a lot to juggle for just one or two final arcs.
