Changing the story is a reboot.
Changing the writing telling the exact same story is a remake.
Those are the choices I think
I would probably read a remake, just as I play remade games to see how much better they became. If you'd do a reboot and abandon your existing series, I'd probably stop reading you. If you want to quit the series, it'd be better to close it, and after start a new one in the same world, but keeping continuity with the existing one.
