I'm like 99% sure Mihawk is going to ally with the RHP in the EoS.
If you believe Mihawk is still Zoro's endgame, then Mihawk has to be associated with some group in the end. On that side, if you believe Shanks is Luffy's endgoal to tie up the series and if Shanks has a much bigger ulterior motive than initially let on, then you can see how this works.
I've never been way more sure than Shanks/Mihawk being the last fights in this series.
