I’d say lower probability, but Snape is the obvious villain right now based on what we know about him destroying the notes
Wait, how is this relevant? Destroying the notes is just about cleaning up his SPHEW-related tracks (due to his apparent embarrassment at being a soft touch w/r/t bullying) now that Hermione and her notes are under great scrutiny as possibly being related to her framing.
And in fact, I’d say the notes are evidence against. If Snape had been plotting this all along, one might expect the notes to have been destroyed before the incident is uncovered, say after Hermione left for the duel, since Snape would not be able to guarantee he’d be assigned to look for the notes, that he would be alone or unobserved in every way, etc. If you predict an investigation will find dangerous papers you no longer need, you don’t wait until the investigation starts!
I don’t see Snape’s motives the same way. Here’s why I think he’s the obvious villain (if my above ‘twist’ is wrong :/):
We know he was behind the plot with SPHEW as the puppet master, and that it centered around Hermione. As a result of his involvement, the bullying situation escalated until Dumbledore had to end it. If not for Malfoy’s involvement at the cafeteria, Hermione would have ended her anti-bullying crusade disgraced, embarrassed, and powerless. The fight with the 7th year had the potential to end things in this way with Hermione as well, but it did not due to sheer luck. It would be poor planning on Snape’s part if he had wanted to help SPHEW in its fight. His presence at the last big fight is not evidence either way; he could have been there to bolster the slytherins or help SPHEW.
In any event, if we look at Snape’s plotting in this light, there are now two people plotting against Hermione if H&C is not Snape. This does not make too much sense to me (from a who benefits standpoint) unless you consider Lucius as an option, but he loves Draco and would not plan something that might kill him.
Destroying the notes at the earliest opportunity is optimal, but the risk of being detected by Dumbledore OR Quirrell OR the Wards OR the Marauders’ Map OR <competent time-turned investigator if the plan doesn’t work> is significant if he tried to do so the night of the duel. His window of opportunity is not too large either, because Hermione would notice if they were destroyed too long before the duel. Perhaps Snape went ahead with his plan, confident in his ability as a Slytherin to maneuver the room full of shocked people into letting him search Hermione’s room?
((Postscript: After I’m done typing all of this out, it occurs to me that I may have latched too strongly onto this theory and am now defending it because it’s a pet theory and not because it’s the best theory. I don’t think that this is the case, but that’s how pet theories feel ‘from the inside’ anyway. Bleah.))

I think it was pretty clear that he was there to help SPHEW. That makes sense given his memory charming of everyone involved and it was (very) heavily implied that he was helping them in other battles.

Edit: Disregard due to reasons below.

I notice I am confused.…
(I reread the Dumbledore conversation speculating that Quirrell was helping SPHEW in previous fights, and that can only be Snape helping.)
He could have memory-charmed if he didn’t want to be known as working against SPHEW, but it is more likely that he was helping.
Now I do not have a good theory for who H&C is.
