I don't think any feelings would have changed for
Snape, just because he hated James and he hated
Harry because he was James' son. However, I can imagine
Harry's feelings toward
Snape changing a bit. I really just can't imagine how the scene would have been had
Snape been living when
Harry looked at his memory. I just find it so sweet that the last thing
Snape saw before he died was Lily's eyes.
Also, like Seeker said, even if
Snape had been living when
Harry visited his memory, I can't see the conversation turning to the Elder Wand at all. Mostly because of
Harry's mistrust of
Snape.
