Luna as a nickname for Eleanor?

I love the name [name_f]Luna[/name_f], and the name [name_f]Eleanor[/name_f], but could one be used as a nickname for the other, and are both getting too common?

I prefer [name_f]Louisa[/name_f] from your list nn luna

Really really really no. They don’t work at all.

Noooooo, they’re two separated names. [name_f]Luna[/name_f] is so pretty and definitely a stand alone name. They do not share the same sound nor the same meaning. No, just no.

Absolutely NO
