Maybe the "original" heros ...
What if sila was able to attain peter's powers, would peter regenerate while sila has the power to gain others abilities without killing them? XD
I think that Peter would regenerate, eventually. We've seen that Claire can regrow some limb-age, and reanimate after a deadly injury (specifically the tree branch to the base of the skull that got her opened up on the coroner's vivisection table).
Peter's ability is absorption, apparently osmotic in form. That is, he acquires abilities by being in proximity to the bearer of that particular persuasion.
Sylar, I believe, does NOT eat or need to consume in any way, the brains of his victims. His talent is more like a bent for engineering. He is fascinated with understanding how things work, and has bent his pursuit on understanding how these powers work, not just how many powers he can acquire, though that is a nice side benefit. Maybe he can get an entry in Ripley's or Guinness Book, eh? lol
No, I believe Sylar needs simply to "see" how something works. And I believe he's figured out that the special abilities of "our next evolutionary rung" of humanity is propagated by a unique aspect of the brain itself. Whether it's a small node somewhere in the brain, or perhaps some pattern in synaptic routing that is visible to him, perhaps because he's seen the brain and now knows just exactly how it works? Who knows, maybe a combination of the 2, your guess is as good as mine.
But it's plain from the evidence, he needs only to make some active examination of a thing in order to determine how it works, most plainly was the first encounter with Prof. Suresh the Senior, when he diagnosed the elder's watch simply by gazing at it (devoting his full attention, probably in an unconscious activation of his latent power) for a moment or two.
So, that's the distinction between Sylar and our redoubtable baby of the Patrelli clan; One requires active examination, which usually requires cracking the brainpan, and the other is totally passive, requiring only nearness to a source of unusual abilities. Acquisition vs. Absorption.
If Sylar was able to peel Peter's melon and get see what he needs to see, then yes, he may be able to acquire Peter's absorption ability. However, I don't think that he would automagically accrue all the powers that Peter has absorbed. Only the power that Peter has to absorb other powers.
Peter may not even die from it, though I imagine it would be a measure more excruciating for him than for most, since his body would be attempting to initiate repairs even while Sylar was ripping him open. Another word on that point, Sylar would then have to make a choice; Should he continue to acquire new powers in his old fashion, or repent of his old methods? And then, if so, would he get the same knowledge of how a power worked, or would it be like looking through a magnifying class smeared with petroleum jelly? Maybe some Claritin could clear it up.

Then again, he may find that it doesn't suit his tastes, and keep on with his "evolutionary imperative."
I think if he stayed in range long enough, he may absorb from Peter all that has been gained from being near others, and that's a lengthy list. But I think it would be more likely to manifest sooner if he left Peter's presence, and even faster if he were to soon come in contact with someone else, who's power Peter had not yet encountered.
As long as Sylar didn't do too much damage to Peter's brain, or physically remove it from it's usual resting place, I'm confident Peter would regenerate, though I don't envy him the headache he will have when he awakes. hehe
