Only if you like the fact that I'd change your class to bard and give you one Wishh a day that you could only grant if someone caught and imprisoned you and forced you to grant it. Or in otherwords you'd be a bard Djinn without all the other cool Djinn Stuff.Okay. I can tango.
I wish to create a new spell called Wishh that has exactly the same effects as Wish and add it to my spell book and cast it with my slots etc etc. now it doesn’t matter if I lose the ability to cast Wish, I can still cast Wishh.
Note since Wishh is exactly the same effects as Wish then failing the roll on Wishh only means I cannot cast Wish.
Do I win d&d yet?
