Oof yeah, screencapping from web sources gets really iffy - I did it at one point for some Voltron stuff from Netflix and a bunch of the stuff didn't even like, render properly to file? Like everything else was there and then the video area just had weird black sections. Thankfully solo has uploaded video files for Guardian (there's a link in the comments on one of the resource posts, I don't have it offhand sadly) and a bunch of people have done fairly extensive screencapping already, even if it's not always of bits useful for cosplay things.

Honestly at least part of what might get me to do it is that I already have a nice black lacefront wig I've used for two other costumes already - otherwise the cost of that would probably be enough to put me off. It's definitely nice to have a cosplay partner, particularly because we have very similar tastes in stories and characters, so we're pretty happy to drag each other into new fandoms and ships. I haven't gotten her into Guardian yet but it's next on our watchlist - I predict Ye Zun will be a fave because she is very fond of 'had a justifiable reason for revenge and then proceeded to take it way too far', haha. I do sometimes wish I could drag more people together to do bigger groups but that involves a level of being connected in the community that I don't have the energy for.
