Of wandless magic and psychological confrontation

How could the last battle between Harry and Voldemort be fought on 
an equal ground when the difference between the proficiency and 
experience of these two wizards is so vast? 

I have wondered how this could be, since Voldemort and Harry seam so 
unevenly matched in a wand to wand battle, apart from the fact that 
they cannot battle with their current wands without the duel being 
over in an incantation or two:

"Priori Incantatem," he muttered... "Harry's wand and Voldemort's 
wand share cores. Each of them contains a feather from the tail of 
the same phoenix."
"So what happens when a wand meets its brother?" said Sirius.
"They will not work properly against each other," said 
Dumbledore. "If, however, the owners of the wands force the wands to 
do battle... a very rare effect will take place. One of the wands 
will force the other to regurgitate spells it has performed—" (GoF-
36).

Now, how could Harry vanquish Voldemort if not in wand to wand 
combat when it is obviously impossible. Wandless magic perhaps?  A 
couple of new prospects are introduced in the fifth book; 
 1) Occlumency: "Now, Occlumency. As I told you back in your dear 
godfather's kitchen, this branch of magic seals the mind against 
magical intrusion and influence." (OotP-24), 2)
 2) Legimency: "It is the ability to extract feelings and memories 
from another person's mind—" (OotP-24), 
 3) And along with them, a prophecy that foretells a different kind 
of power... "The one with the power to vanquish the Dark Lord 
approaches.... He will have power the Dark Lord knows not..." (OotP-
37).

Still, exactly what power this is cannot yet be identified with 
certainty; we only know what Professor Dumbledore himself has told 
us: 

"There is a room in the Department of Mysteries," interrupted 
Dumbledore, "that is kept locked at all times. It contains a force 
that is at once more wonderful and more terrible than death, than 
human intelligence, than forces of nature. It is also, perhaps, the 
most Mysterious of the many subjects for study that reside there. It 
is the power held within that room that you possess in such 
quantities and which Voldemort has not at all. That power took you 
to save Sirius tonight. That power also saved you from possession by 
Voldemort, because he could not bear to reside in a body so full of 
the force he detests. In the end, it mattered not that you could not 
close your mind. It was your heart that saved you." (OotP-37).

Here is where I find a glimpse of hope that could determine the 
outcome of the last battle and the success of good against evil. We 
learn here that Harry indeed can NOT be possessed by Voldemort 
(which is an ability that we have seen The Dark Lord is very 
skillful at, even in his early years) and this means that Occlumency 
is not a necessary tool for Harry to protect himself from 
Voldemort's control in the future.

Voldemort has been able to harvest these abilities since he was 
young, and in his imminent downfall at the hands of the one year old 
Harry Potter he has also transferred some of his powers. Could it be 
that along with those powers Voldemort's magical mental abilities 
and capacities where passed to Harry as well? Could Harry be able to 
invade Voldemort's mind later on?

Now this is an encouraging thought; if Harry does indeed have this 
ability, the last battle could very well be fought in a 
psychological and emotional way, by an invasion of minds and a 
battle of willpower, escalating to a struggle of the Dark Lords 
hatred and Harry Potters love, a final battle of emotion. 

At this point the power that Voldemort knows not, could surface, 
Harry could invade Voldemort's mind (since Voldemort himself cannot 
enter Harry's) and give an overdose of not only that which Voldemort 
can't stand, but that which he has never been able to understand, 
love and affection for another human being. Here Harry could very 
well gather up all of his love and grief, along with all the 
affection he has for his friends, and overload Voldemort on them, 
making him live through his eyes and memories, revealing all that he 
has done from the eyes of the one he has affected the most, Harry.

This could be a faith worst then death for a person as empty and 
lacking of real emotion as Voldemort, this could be the end of 
Voldemort, a suitable end. Giving Harry the opportunity to vanquish 
him (not kill him) and keep hold of his moral integrity...

I hope this hasn't been discussed, I am new to this groups and this 
is my first post. I am eager to hear your comments.
