Mayoral Chain and the Queen

Our Mayoral Chain has a central link for her Late Majesty, which is a side view. We are now in conversation about getting a new one for the King. The question I ask is is it permissible to move her majesty to another prominent position or should she be taken off the chain to be put on display in our Civic Museum. This subject has not come up in 70 years so no one here knows the answer. However I have never seen a link of King George.
