we can't agree on a middle name for good reason!

So me and my husband can't decide on a middle name if we have a girl. I don't know what I'm having yet but either way we have a first name. Our two year olds name is Austin Kal-El; Austin after my late father and Kal-El is supermans birth name (my husband is a huge nerd haha) I love his name & we agreed on it right away. We've agreed that if we haves girl she'll be named Susie after his later mother but as for the middle name my husband wants to be Zor-El which is supergirls birth name....I'm just not a fan of the name. I get the theme and it'd match our sons name but I just don't like it /: does the name sound as ridiculous as I think?
