I think, If we assume that W. D. Gaster is a cannon character, and not just some cut content, it's highly likely that Sans and Papyrus were created by Gaster, like you said. Judging by evidence from both of their boss fights, it's safe to say that the skelebros weren't imbued with the same traits. I'm guessing that, along with determination, Papyrus was probably imbued with kindness and perseverance (judging by his behavior in the game). Like I said, perhaps the trick to creating life (that can feel emotion, unlike Flowey) without a SOUL was to add different traits, as humans are obviously made of more than just a single trait. As I mentioned before, the only known object to become animate after recieving an injection of a human trait-- in this case, determination-- is one that came from the human world in the first place, I assume that the corpses were human, or are at least made of human parts. As for why Sans is aware of the distortion of his world's timeline, and Papyrus seems to be blissfully ignorant of just about everything, I speculate that is Sans' doing, not wanting his more innocent younger "brother" to have to carry the same burden.

Anyway you look at it, though, the skelebros have some connection to Gaster. Unless Toby Fox gives us confirmation on their origins, we're kind of stuck with conjecture.

And I realized, after re-reading your post, that I linked you to the exact same video you were talking about, and I feel silly. I guess I should pay better attention. ^ ^;
