Frankly, I think cutting Canto Bight and DJ out entirely cripples Finn’s character too much, since he’d basically vanish from the story for a massive stretch of time. I don’t think you can get it down any more than Hal did for Legendary (which poppasketti replicated for Rekindled) without it feeling like a fan edit and not a finished film (much like attempts I’ve seen to remove Jar Jar entirely from TPM or removing the Ewoks entirely from ROTJ).
I actually thought the theatrical film felt like a fan edit. The entire side-plot trip to Cantobight, being stuck in jail, and then the time to return and sneak aboard the Supremacy, just didn’t fit with rest of the narrative in regards to time. It felt shoehorned in and made The Supremacy chase feel like slow motion. Speaking of shoehorned in…that Maz Cameo… ugh
