I put Kylo meeting the Emperor at the end of VII, personally. This recontextualises Snoke, as well as giving motivation to why Kylo feels he needs Rey: he knows that Snoke is a puppet. This also gets rid of the silly cliffhanger with Luke, especially as that sequence is repeated in TLJ (which I also extended to show more of the buildup from TFA).

To me, this helps focus the trilogy more into a three act structure and deepens the motivations of Kylo (and why he flips from Supreme Leader to Palpatine’s lackey so quickly: he failed to get Rey to take his hand and help him overthrow the Emperor).
