Have you thought about the possibility of having 2 godmother's... or 2 full sets of godparents?? I am a joint godmother to my bf's little boy, the other is his aunty. To be honest, these days it's all a little different and the whole thing is not really what it used to be. The godparents don't actually necessarily get the child/ren. That should actually be covered in your will. Anyway, just a thought
