How to move my item slots around

Looking over the items I’m going to want for my character, I find myself wanting two neck slot items (an Amulet of Mighty Fists and a Necklace of Ki Serenity).

The Hand of Glory allows a character to wear an extra ring by taking up third neck slot, are there any other items that exchange what slot can be used where? (Hopefully one to let me wear more than one necklace at a time?)
