I don't see why not hun.... I don't know a huge amount it all but I think it would make more sense to have 2 beautiful people in her life who can help role model and mentor her than someone who is around now but may not be later. Up to you and your DH but I don't see any issue unless it is that she won't have a "male" figure as a godfather. Having said that, we don't have godparents in my family and there are always people who step up as needed as kids get older. Good luck making your decision!
