Hey there!
After discussing your idea, we have unfortunately decided to decline it. Not many players buy the beard, so we do not think the walking cane would be very popular either, considering most players are fairly young and would likely not be interested in something like this. We also do not think it would be very interesting, as it might just end up being a simple stick, as we are not sure how this would be fancy. Technically, staff wand apperances can also be viewed as walking canes, as they can be used as such in certain situations.
Additionally, it does not make much sense to cast spells with a walking cane, unlike when casting with a staff, as that is a more magical object.
Nevertheless, thank you for bringing up your idea to us. We really appreciate it and would appreciate any future ideas from you even more!
Enjoy your day!
