Setting animated wallpapers, using image files (crossfading)?

I want to sort of recreate macOS 15's dynamic wallpaper, and downloaded this set of 8 wallpapers which are most / all the colors it cycles through. On Hyprland, I want to cycle through them throughout the day, but also slowly transition from one wallpaper to another for an hour or longer, crossfading / blending them.

I did some searching, and neither timewall or adi1090x/dynamic-wallpaper can do it. I looked at making my own script to blend images once every 60 secs, but I'm not sure how to quickly crossfade images. This command takes ~15 secs, I feel this should possible much faster with or without imagemagick: magick composite -blend 50 wallpaper1.png wallpaper2.png output.png.
