Have you thought about in-universe explanations for why Crowfeather (infected king!) was the only member of the Sundrown patrol to receive an Honor Title? Especially Tawnypelt, because I recall you mentioning she was leading the patrol at one point! In a perfect world I imagine they'd probably all get one, but I figure you can't just go around changing major character's names willy nilly like that.
In a perfect world the names would all become Honor Titles but yeah I try to avoid renames. I COULD be convinced to giving Tawnypelt an Honor Title though.
If I gave her an honor title it would be something like Tawnytreader, Sunsetchaser, or Sunsetter. It's in reference to how she eventually leads the Great Journey west through the mountain, towards the setting sun INSTEAD of directly North to the Lake, so that the Clans could meet with and get supplies from the Tribe of Rushing Water. Her leadership of the Sundrown Patrol and leading the Clans during the Great Journey makes her an immediate hero.
Brambleclaw probably gave up his Honor Title purposefully. He hesitated when Firestar was in the snare, and Mothwing leapt out of a bush to free the dying leader. He's ashamed of his inaction, so I think it's actually very poignant of him to say;
"I understand why you're taking away my deputyship... may I also ask for you to take this title from me?"
"But why, Northheart? You want to become Brambleclaw again?"
"...I was happy to have broken from his legacy, at first. But now I don't think I ever will. I think I need to be reminded of where I came from, or else I'll put it too far behind me."
Like, really drive home that what I'm doing here with Bramble is a tragedy. Everyone WANTS him to get better, to be good at self-reflecting and make good choices. They want so badly for him to break free of his father's association and be a positive representation of his powerful bloodline. Be he never does.
It doesn't bring him joy to be the way he is. And there's times he's so, so close to realizing that he should stay away from power. But time and time again, GIVING him that power is a mistake, and on his end, he always takes it.
"Northheart" isn't as punchy as it could be though. I have to think about it...
(Especially since I like how in canon, the "bramble claws protect the camp" prophecy could have applied to Thornclaw just as well. Maybe I'll change it so it could have applied to Brackenfur somehow)
Small recap: after their deaths, every member of the patrol is exalted and will become Directional Patrons. The two tagalongs also get associations.
Tawnypelt: West, towards the Ocean
Crowfeather: East, towards the Wilderness
Brambleclaw: North, towards the Lake
Feathertail: South, towards the Tribe
Stormfur: Patron of those who Leave (he is not joining StarClan though, these prayers go, symbolically, unanswered.)
Squirrelflight: Patron of Missions, most often invoked for Salt Patrols.
Stormfur didn't get a title because the leader at the time was Leopardstar. She wasn't very reverant of the mission to begin with, and Stormfur never returns to RiverClan after she let him be exiled by the False Sign.
Squilf actually does have an Honor Title-esque name in Clanmew! It's Pishkafsheek; "Red Squirrel Soars (like a bird of prey)." "Sheek" isn't regularly used to describe prey movements.
