We deffo need a plural of moose that isn't moose.
Think of the poor gerbils - if they are told 'This tray of Tunnock-based cocktails is for the moose', how are they to know if it is intended for AgileGold, who has ordered drinks for all of her new-found chums < thank you, jolly kind, don't mind if I do> or all for Inky who is drowning her sorrows because she is no longer the only moose in the village, OR is intended for both Inky and AgileGold who by now have bonded and are drinking to being new best <hic> friends.
A Bluestocking plural is definitely needed. I suggest 'moosen'.
