Well I will say that in theory doing this was possible on the old server but the shopmenu used to be used less before you could enter the items names in chat to buy them.
With that logic restricting the shop menu would actually be a change from how it was... perhaps I could make it so that cloak for that race only lasts X time or something. I could also make a slight change so that it crows when it lands and takes off. This or having it randomly crow could help make it more balanced while at the same time enabling all the fun.
In fact this could make it more inserting in that people would be listing for the crow should to help locate the bird.
