Godparents dilemma!

I really want my sister to be the godmother of our baby cause she is all the (close) family I have left. Both my parents died and now it's just the two of us left. She can't have kids of her own although she looooves kids (she's a kindergarten teacher). But my husband says if we ask my sister we HAVE to ask his Brother to be the godfather. And that's where I see a problem... When we announced our pregnancy he told us he was not happy we were having kids cause from now on all family dinners will be too loud. He and his husband (they are gay) hate kids. They do not want kids of their own and everytime they see a child they are eyeballing cause they find them so annoying. They refuse to sit next to their 10 and 12 year old nephews at christmas diner. No kids allowed at their wedding etc... I have no problem with them not liking kids (each to their own). But why would I ask him to be the godfather of my child. Just to please my mother in law (who I adore btw)? My husband says it would hurt her if we asked my sister and not his Brother. I can see where he's coming from but uhg... I really don't want it to be him. 🤣
