I like the idea and it sounds like a great way to combine the best bits of those two stories, but it’d very much be a “new” story, right? Obviously fanedits are inherently unfaithful, revisionist etc, but it seems to me that this goes a little further than just intercutting two arcs - which still depicts ultimately the same events - or cutting material out of an arc to streamline it while telling the same story. This would be showing objectively different events, and I don’t think I’d personally recommend someone’s first experience with TCW be one that involves non-canonical stories being told using completely recontextualised footage. Don’t get me wrong, it sounds like something I’d enjoy watching, I just question whether breaking canon to this extent is entirely in line with the project’s goals.
