More GUI Textures (Please)

By default under Renoise v3.1.1 there are only 5 textures for themes. And imho, only the “Jeans” one is a bit more cool but not really amazing. So I searched this forum and found somes really nice textures, for example here: The issue is that these textures don’t work under Renoise v3.1.1. Do you know if there are technics (or even better a tool) to convert old textures to new textures? Thanks…
