Was thinking of maybe using some footage from this short fan film to improve Canto Bight? Boba Fett is in a dark bar/gambling/saloon like setting, and he shows a hologram (looking for a bounty.) If someone could use some VFX work to change the hologram from that character to Finn (from the “its weird that you recorded that” Scene, we could make it seem that Phasma has sent a bounty hunter (A Boba Fett who survived) to look for F12187, so she can exact revenge.
It could also imply that there is indeed a spy in the resistance, (shows how Fett got the hologram.)
