Hello Aternos,
Origins SMP is a way lighter version of the Origins Adventure modpack. It works better for laptops so it is upsetting to not see it on the modpack list. I really enjoy this modpack so I hope it can be added.
I don't know much of the technical aspect of modpacks so I'm not sure what files you are looking for. But since this modpack was previously denied for no files, it seems like there are some files on the link I sent.
Hopefully that will work for you,
Thank You!
