Yay! Finally, someone is reconsidering [name_u]Alexis[/name_u] on a boy. I think it is great. 
I am staunchly in the girl camp, but probably mostly because all the Alexises I have ever known have been girls, however my brother and his fiancee have [name_u]Alexis[/name_u] at the top of their list for a boy.
[name_u]Alexis[/name_u] I think is unisex and I think of a Russian boy or man, I think it was on a movie or something
