Heya! This has already been suggested before:
For a snidget: https://potterworldmc.com/threads/trainer-snidget.3565/
For a bruiser bat: https://potterworldmc.com/threads/add-a-bruiser-bat-to-the-flying-gear.1978/#post-29913
The second one was declined because it's abilities would not really fit the gameplay of Potterworld outside of the quabbleball minigame, and it would not make sense to have these items outside of quabbleball games and I believe this also applies to any other quabbleball gear.
Thanks for making a suggestion for Potterworld, as we really appreciate that!
Have a great day!
