I've definitely heard about GPrime85 & Blackpilled/Devon Stack talk about the paucity of RW art, the reasons for it & the difficulties of trying to fill the void.

Can't recall any specific conclusions or solutions though.

Devon Stack did just create an experimental AI parody about American Indians killing IRL settler missionaries called the Whitmans. It wasn't my cup of tea, but he was very proud of the work he put in (apparently worked on it without sleep for a few 24 hour cycles) and talked about how similar projects will likely be important to push white nationalist narratives in the future in the slop wars.
