[LOTR] Can someone wear all 3 Elvish Rings of Power at once?

Would their hand explode? Would their mind melt? Would they be totally fine and become ridiculously awesome from the Rings' combined power?

Im sure it could be done. In *Unfinished Tales* Gil-Galad wore two of them, Narya and Vilya.

The three rings had different powers. 

Nenya, The Adamant Ring worn by Galadriel, had the powers of Preservation, Protection, and Concealment from Evil.
Narya, The Ring of Fire worn by Gandalf, had the power to inspire others to resist tyranny.
Vilya, the Ring of Air worn by Elrond, was said to be the mightiest of the three, but no specific powers were told of it, but it may have the power of healing.

All three rings give the wearer resistance to the weariness of time, as well as the ability to hide from remote observation (save for from The One Ring)
