One of the easiest fucking answers that could be implemented right God damn now is letting them finally control their own lore.
Give the lore bible that Cover clearly has hidden somewhere in their office to the biggest lore autist mane, the hardline "no you can't do this" rules, and let them do whatever. It's batshit insane they have a whole setting that they can play in and are told "no, don't so this creative thing". I've even see people who hate the boys ask why they don't do anything with their lore.

Yeah, how nice Armis can do those, but I'm talking about Tempus here. Shinri's monthly or whatever radio news drama about their world, the menshi comics/wallpapers Axel wanted to commission that was missions they went on, in-universe songs or 3D shorts, asset commissions, etc. They could do so much shit to build their own brand and add on the streamer/idol aspects to it.
