The Sorting Hat

  The song the Sorting Hat sings in book V has been troubling me for 
awhile now.  The song identifies the division of houses as a major 
problem.  

>>
The Founders of our noble school
Thought never to be parted:
United by a common goal,
They had the selfsame yearning
To make the world's best magic school
And pass along their learning.
"Together we will build and teach!"
The Four good friends decided
And never did they dream that they
Might someday be divided,
For were there such friends anywhere
As Slytherin and Gryffindor?
Unless it was the second pair
Of Hufflepuff and Ravenclaw?
So how could it have gone so wrong?
How could such friendships fail?
>>

Perhaps the solution to the problems faced in the WW is to return to 
those original ideas of united goals.  Once the houses were divided 
Slytherin grew upset with the other houses and left.

>>
What with dueling and with fighting
And the clash of friend on friend
And at last there came a morning
When old Slytherin departed
And though the fighting then died out
He left us quite downhearted.
And never since the founders four
Were whittled down to three
Have the Houses been united
And they once were meant to be.
>>

The hat clearly states that the fighting ended after Slytherin 
leaves.  We've discussed at length the possibility of people 
switching houses to unite the school.  In theory, the hat tells us 
exactly what has to happen.  All four founders have to return to 
Hogwarts to lead a united school.  

How?  

Time turning? Possible, but I think this is unlikely because its 
already been used as a major plot device.

I think the existence of Tom Riddle as the heir of Slytherin gives us 
the likely answer.  In COS JKR gives us the clue that Harry is the 
likely heir to Gryffindor.  Who are the heirs of Ravenclaw and 
Hufflepuff?  I think Luna is a possible answer.  Sure she's a fun, 
likeable character, but everything she's done in Book v could have 
been accomplished using an already established character.  JKR gives 
us a Ravenclaw who is accepted into the inner circle.  I imagine that 
a similar Hufflepuff will be introduced or come into the circle in 
Book VI.  All of this points to LV having to return to Hogwarts 
(unless he has created his own heir already)... could be 
interesting.

Sorry for the diatribe!

Lady McBeth, who thanks you for bearing with her
