Dont have it in front of me so instructions might be off, but Audacious can load any winamp skin you download, it is available as an option in the customization settings. You might have to drop it into a skins system folder on audacious, but winamp skins are one of the theme options you can pick on audacious. Looks just like winamp but the backend stuff is different (right click menu’s, etc.)
I’ve decided due to running into issues as well, that my system being built on x11 for a few years means I probably wont switch to wayland until I do a fresh install to avoid any potential issues around old x11 packages i’m running
