Shmendrik
“I am considering instituting this minhag among my chaburah but would appreciate input from the hamon am.”
1)Why would you want to institute a new minhag at all?
One who has a minhag should keep to it.
The exception being: one who has no minhag or knows that it was lost.
2)If the case where the adoption of a new minhag is indeed warranted, why would you decide based on the opinion of the hamon am? I would suppose a close rebbie or rav would be a more appropriate address.
Minhagim are not to be trifled with. Chanuka should remind us that during a time of shmad one must give up his life even for the sake of a minor minhag.
