Have I just transfigured out the Horcrux!Locket?

Meanwhile in a parallel universe, where Snape is ESG! and Draco was 
never given the task to murder to DD, Harry is sitting opposite a 
revived Dumbledore. The locket lies open on the desk between them, 
the scrap of parchment unfolded next to it.  Dumbledore is 
contemplating them, his elbows on the desk, with the tips of his 
fingers resting against each other.
"But Professor, we've failed, it's not the real Horcrux," says Harry 
despondently.
After a short pause, Dumbledore smiles, and looks at Harry over the 
top of his glasses.
"You think so, Harry?"
Harry looks puzzled.
"Think again, Harry."
"Are you saying that this is the real Horcrux?"
"I am absolutely positive it is."
"Then what about RAB?"
"Well, that could be Really Any-Body."
Harry is still looking puzzled.
"Remember, Harry, Lord Voldemort's skill in persuading others to 
believe what he wants them to believe, and I rather think he has 
succeeded with you," says Dumbledore gently.
"You mean," says Harry slowly, "that this is part of the protection 
of the Horcrux?"
Dumbledore smiles encouragingly.
"So in fact, this *is* the real Horcrux, but he has 
 transfigured 
it to look like a fake horcrux and put that note in it to mislead 
anyone who found it?"
"I rather think he has, Harry."

So, I there you have it.  RAB is *not* Regulus Black.  No-one had to 
find the cave.  That whiz-bang potion is Voldemort's.  Harry has the 
real Horcrux!Locket.  It's not important where the unopenable locket 
in Grimauld Place is, and the whole Mung thing is either a red 
herring or part of another plot thread.  IMO, if it is relevant at 
all, Harry will finally track it down and find that it is no snake 
on it, which may prompt him to think again about the locket that he 
has.

Also, according to DD, only Voldemort, DD and Harry (possibly 
Slughorn)know that Voldemort has made more than one Horcrux. The 
note reinforces the idea that there is only one horcrux out there, 
and if imaginary RAB had destroyed it, then whoever found the fake 
one, if they survived, would be tempted to try and kill Voldemort, 
thus breaking their cover and revealing themselves as his enemy.  I 
think this might help solve the puzzle of the potion.  But that 
needs thinking about

It always puzzled me why JKR deliberately had both Harry and 
Dumbledore not have time to notice the locket. For me, as a reader, 
the discovery of the fake!horcrux did not sit well *after* DDs 
death.  I was so blown out by his death, that I found the discovery 
of the Horcrux almost annoying in taking my attention away from it.  
But, now it makes sense to me, because DD would always have 
suspected the locket to be the real one and would have told Harry so.

Opinions please!

Who in the cold light of morning is thinking her Big Bang Theory of 
Powers!Horcrux, turned out to be a bump in the night.  But oh well, 
I feel somewhat compensated by sorting the locket out - to my 
satisfaction anyway.
