There are MANY downloadable mods for DDLC, and many people making mods right now (I'm doing backgrounds for 4 different mods at the moment).
I don't know if there are any of the mods here on itch.io, but there are on reddit r/DDLCmods.
something like 300+ mods ready to play at the moment...
You may find someone to make this, or there are instructions on how to make your own mod as well.
