How can I use the Mod Minecraft Sky?

I would like to release a Sky Modpack. But in order to spawn in the sky on a tree, I would like to use the Minecraft Sky Mod. Of course, I'm not allowed to put a pack of this mod online by copyright because I will not get approval. How can I do it anyway? PS: I can't program at all, only merge Mods

The "Minecraft Sky Mod" which exactly of the umpteen different Skyblock mods? The ones from the Youtuber project? Of course you can use that. They did not write that themselves. These mods are public and may of course be used.

Thank you. I meant the mod that makes you spawn on the tree. That is not public but only in this pack available. Is that possible?

Of course, the public.
