I could, but if you are having performance issues, ill suggest using a few other mods, that just increase the performance of the game in general. They are: Sodium, starlight, lazydfu, iris(if you want shaders). They are all fabric mods, so you can use them with the carpet mod itself. And i believe with these mods, the game should run faster for 1.17.1+ than if you played completely vanilla in 1.14.

And sorry i cant attach the mod to a datapack, or just convert it to a datapack, as I would have to rewrite the whole "player" spawning code in which is written in java, to the code use in Minecraft aka commands. That would slow down the efficiency of the mod by a huge amount, and it wouldn't be worth it. So sorry!

Ya, cause it wayyyyyy too hard if its done without mods.
