Parallel between the Potions Puzzle and the DADA teachers?

There have been so much theorising about what the bottles in Snape's 
riddle symbolise - Dave Whitley's essay and an excellent post by 
dcgmck, for example, compare them to the players of a Quidditch team 
and to the books (# 106768) and are so close to a hunch of mine that 
I'm almost hesitant to draw further parallels. Anyway, I'm just 
throwing this development out to the lions (fellow list-members, I 
meant to say) for discussion.

Three of the bottles are poison.
Two of them are nettle wine (duds, if you will).
One of them is aimed backwards, at the past.
One of them is aimed forwards, at the future and Voldemort.

Granted, the potion bottles could symbolise almost anything that 
comes in groups of seven (like a Quidditch team), but I'm going to 
try it out on the seven DADA teachers. For the sake of this argument, 
I'm going to suppose (and I don't think it's unreasonable), that 
there are going to be two more DADA teachers at Hogwarts, the last of 
whom may or may not be Snape. (I'm leaning towards the latter - if 
Dumbledore doesn't think it's good for him to teach DADA under 
fourteen years of peace, I doubt he's going to change his mind after 
Voldemort has returned. And Harry is out of the reckoning.)

DADA teachers symbolised by the bottles of Poison: Quirrell, Crouch 
Jr and Umbridge.

DADA teacher symbolised by nettle wine: Lockhart. (Besides, after 
enough alcohol you're going to feel like you've had your memory 
modified.) :-)

DADA teacher symbolising the past: Lupin.
(This is somewhat open to interpretation: it was Lupin who taught 
Harry the Patronus charm and gave him incentives to grow, but he was 
also the one who provided Harry with the first personal connection to 
his dead parents.)

This leaves one "nettle wine" teacher and the one who will guide 
Harry to his goal, in other words Voldemort. On the other hand, if 
these assumptions are correct, the "poison" quota is filled. The most 
probable scenario, I think, is:

Book 6: Nettle wine.
Fudge may still cause difficulties. I can all too easily picture a 
scenario where the Hogwarts staff and students want Lupin to return 
while the Ministry and the Board of Governors back some gormless 
individual whose only advantage is *not* being a werewolf. On the 
other hand, if Dumbledore changes his mind about Snape and DADA, 
Snape could be the one who finds himself as being subjected to 
prejudice.

Book 7: The crucial one. I hope for a competent teacher who could 
both create new hope in Harry and lead him against Voldemort.

Thoughts, anyone?
