Hi Resznotes, thats is actually very common when switching between backhand and forehand to make a slight grip change and adjustment, even some professional players make these changes.
A small change is fine, as sometimes it’s hard to feel comfortable with exactly the same grip for both, as long as this change isn’t too big and slows you down when switching and between shots I wouldn’t worry about it too much. Of course just try to minimise and be sure to save as much time as you can while staying comfortable for shots on both sides 🙂
