@Sly11, thanks for the comments. So, if I'm understanding this correctly, Rogue One TK would remain the same. However, due to the other variants coming forward in movies and shows, "Anthology Stormtrooper" would be created as a separate CRL. The only problem I foresee is when we encounter shiny white TKs in the Anthology movies and Disney+ shows, which other than the weathered guys, is the same costume as the ROTK. Additionally, Rogue One is an Anthology Movie. This is why I was in favor of a new name and agree with Jeff's comment below.
Remnant Stormtroopers:
I don't recall any instances of weathered R1 style helmets in the show. If they're out there, I couldn't find them. However, in the Mandalorian, we see two variants of TKs, which I suppose could all be called Remnants, but thus far, we haven't seen Disney/ Lucasfilm market them that way. They have intentionally referred to one as Imperial Stormtrooper and the other as Remnant.
Again, figures shouldn't be used as a basis for a CRL, I use this only to illustrate the direction they've gone with marketing, product development and apparently canon reference. If someone picked up a copy of Pablo Hidalgo's "The Mandalorian, The Ultimate Visual Guide" before it was yanked off the shelves, please let us know how this was handled. Were Remnants referenced?
I agree with both of these comments entirely. Ultimately, I feel "Stormtrooper: Anthology" is sufficient. The CRL "Context" would likely read "Rogue One: A Star Wars Story, Solo: A Star Wars Story, The Mandalorian: Disney+ Originals, or you can remove "The Mandalorian" and leave it as "Disney+ Originals." Also, if the remnant costumes show up in a BBY era show such as "Andor," I'm curious what they will be called.
Ok, so last comment. I'm willing to finish my Jimi kit and put it up for the Remnant CRL. Now, I've been doing a lot of "crazy" stuff to it in order to get it as accurate to the screen used costume as I can and my intent is to bring it up to Centurion. But, I'm supposed to be receiving an OT helmet in the near distant future and am willing to go forward with it. I'll continue building to the Centurion standard, but now thinking this could help in establishing a level 2 and 3 CRL later down the road.
