Room of Requirement and Hidden Horcruxes

My apologies if this topic has already been discussed.

Could one of the horcruxes be hidden in the Room of Requirement?  We 
know that the room can only be discovered by someone who is in need.  
We know that Lord Voldemort wanted to return to Hogwarts to teach 
Defense against the Dark Arts.  Dumbledore knew that his primary 
reason to return was not to teach but to recruit future Death 
Eaters.  Could other reasons be that he wanted to hide his completed 
horcruxes and/or find Hogwarts relics (assuming LV already knew 
about the room)?

The book cover for Deathly Hallows (UK Children's Edition) appears to 
show Harry, Ron, and Hermione being hurled through a circular doorway 
into a room full of "treasure."  Could the Room of Requirement be the 
room where the "treasure" is contained?  

After reading (again) Chapter Twenty-Four (Sectumsempra) of the Half-
Blood Prince where Harry is attempting to hide the Prince's copy of 
Advanced Potion Making in the Room of Requirement from Snape, there 
were key thoughts/words that caught my attention:

"I need a place to hide my book." (Harry attempting to open the door)

"...objects hidden by generations of Hogwarts inhabitants." 

"Harry hurried forward into one of the many alleyways between all 
this treasure."

"He opened one of the cupboard's creaking doors.  It had already been 
used as a hiding place."

I can't help but to think that in book seven, Harry will need the 
Prince's copy of Advanced Potion Making and possibly discover hidden 
clues to another horcrux.

Just some thoughts.
