You should watch Smudger9’s TCW Episodes I-V tv-to-movie edits to get a basic idea of what he did, and then decide whether to either continue your current plans or rework the idea to be a continuation of his films. His plan envisioned a 9-movie saga, and started his edits before Canon Season 7 was announced. Maybe this edit works best as 12 movies rather than 14.
I am aware of his edits, however I feel like our goals differed somewhat (at least I don’t agree with some of the decisions he made, especially the grouping of episodes in the first few movies). I want to adhere more to the official chronological order to be easier to follow, and also want to remove as little stuff as possible as I said in the post. However I did get inspiration from some of his edits, especially the Nightsisters/Maul movie, and merging Mortis with the Citadel arc.
