[Fullmetal Alchemist] What would an Alchemist see if they were to use a fully-formed, perfect Philosopher's Stone to pay the toll at the Gate?

The Elrics' share of the Truth was limited by eqivalent exchange- would going into the process with a Philosopher's Stone as your toll permit you to actually understand Human Transmutation without losing anything about yourself?

A perfect philosophers stone is payment enough for everything beyond the gate. 

But knowledge is infinite. If you were to pay such a price, your reward would be infinite too. 

You would never walk out of the gate.
