Hickengruendler:

But in the chapter "Lord Voldemort's request", Dumbledore clearly 
implied, that the reason why Voldmeort wanted to have the position as 
the DADA-teacher, was to get his hands at the Sword. He even 
confirmed it later in the Horcruxes chapter, when Harry asked. That 
means that at this time, which was even before James was born, the 
sword was already in the Hogwarts' office.

That said, your theory is still pretty interesting. But it must have 
been something else that was hidden in the cloak. Not the sword.
