>>716150565 (OP)I think everything would be mostly fine if you just skipped the epilogue and super saiyan Kerrigan.
You could keep everything else, upto and including Amon.
The sole purpose of 'redeeming' Kerrigan should have been to prevent her and swarm from being controlled by Amon. The base campaign of LotV already ends with Amon being defeated. You don't need the epilogue. Would it be perfect? No, but it would avoid the biggest problems.
