There would have been no point in taking all of Zero's memories as the reason she did it was so she wouldn't have to worry about him as it was his love for her that was starving Zero and making him close to falling to Level E. If she had taken all of his memories he would have been as helpless as a child just like she was completely helpless after her mother suppressed her memories and made her human and it would have defeated her purpose.
I don't see any reason why Zero can't move on and find someone else when he has a ton of people that care about him and would support him such as Maria, Kaien, Yagari, Kaito, and Yori to name a few as all of them have demonstrated concern and caring for Zero. In my opinion if he is not capable of moving on with so many people supporting him it would make him look pretty stupid and pathetic much akin to how Sasuke looked back in the first half of Naruto when happiness was staring him straight in the face and he ignored it. I think that his new purpose would have something to do with managing the hunter's association as the next president (if he doesn't recover his memories) or striving to make bring the vampire and human worlds together because its what the girl he loved would have wanted (if he does recover his memories), similar to how Kaien changed as his personality was once a lot like Zero's.
I thought that Zero would fall to Level E anyway? He never got to drink Shizuka's blood. All Yuki did was delay it with a temporary solution, then what?
The reason I said that it would've been better for Yuki to take "everything" is because it would give Zero more initiative to start over. Since only his memories of Yuki were taken away, it was basically only his happy memories that were taken. I might be wording this wrong but I can't seem to put it in a different way... *thinks harder*
But anyway, that same reason also accounts to why I don't think Zero would be successful in moving on from his past. Almost all his life he's been suffering and his only goal is to kill all the pure bloods. However, all the pure bloods have already made plans of their own and will die the way that THEY wish to die. Zero doesn't have any say in it. What will he think of himself? A failure? Someone who failed to get revenge for his family. And with the way he was acting to his classmates at the Academy, do you really think that he wants to move on? Do you really think that he wants to love someone? He's someone without any happy memories so why wouldn't he want to just kill himself once his "purpose" in life has been accomplished?
Also the last part of your post doesn't make sense. Why would Zero want to ever bring the vampires and humans together? Vampires made his life miserable, there's no way that that's gonna happen. Also you should already know that he doesn't want to be the Hunter Association president. He is disgusted with himself for being the very thing that he despises. He's a vampire. Yet, another reason that he wouldn't want to live longer than he has to.
