Help me settle a naming debate with my hubby

My husband(54M) and I(22F) are expecting our first baby girl in February. Hubby mom is named Tonya, so he wants our daughter to be Toya to honor her. However, I want to honor my mom (Collette) too so I suggested ToyaLette. Hubby is completely opposed to the idea. He says that the name is something a Gen Z like myself would choose. I think he’s just being selfish and wants his mom’s name used only. I told him that our daughter will have TWO grandmas and both deserve to be honored.

Please tell me how to convince my hubby.
