Extremely slightly obsessed with the implications of TIES not being in 3rd Life-
Like literally ALL of them were in Dogwarts at one point or another, and I feel like the fact that there were so many of them was kinda what elevated Dogwarts to be as powerful as it was. So either people who weren't part of Dogwarts initially were a part of it in dbhc or they weren't NEARLY as much of a threat to the other factions as they were in canon.
The Crastle Alliance as well involved Impulse and Tango, so they're also cut in half in dbhc (which kinda makes me ponder a world in which Dogwarts and the Crastle fused into a single faction 👀)
Jimmy wouldn't have lost his life in Dare to Flare but honestly he'd've prolly lost it anyways to something else so that's not too much of a difference XD
There's probably also more butterfly effect stuff that I've missed by not watching TIES' povs but I am very interested in seeing what you have in mind (if you ever choose to expand on it in the future). I'm very curious how the clock plays into it...
(Also as an added ponderance, I can't help but wonder if Etho Hopper Clocks have another name in this universe since Etho wasn't alive to make them (or, for the funny route, if Etho was named after the clock instead of the other way around XD)
