Is it morally okay to recreate people from memory.?

There was this one girl Rebecca I really liked in university and she was as perfect and imperfect for me, but we never had the chance to be together although we both knew we liked each and we were friends, more like flirts. And so five years from then, im in a different country on the other side of the world, and my career is going well but my relationships aren't and honestly I feel kind of lonely, and since I can't get someone decent in life, I was wondering whether it was okay to recreate her from memory, from a picture, from an essay she wrote, and moments we were together, like recreating her personality. So that I feel less lonely, and get the chance we never had to be together. Like she isn't physically there but her spirit is. I know it sounds crazy but its people saying, "hes dead, no he isn't hes with us everyday in hearts and minds"
