Sorry, you'll have to redeploy. As carlolm's link shows, you can make ways to actually upgrade your contract in the future.

Here's an article on forking a token which is sort of what you're trying to do: https://medium.com/@edmundedgar/what-happens-when-you-try-to-fork-an-ethereum-token-863e3defcf7
