Changing Overworld Dimension ID

This is related to https://discord.com/channels/935560260725379143/1358501679548596295 In which I am wondering if it is possible through datapacks or mods, to change the overworlds map file to a new name/ID and create a new overworld dimension so that lithosphere/wwoo only affect the new generated overworld. My thanks to anyone who helps me with this.
