Do you have a diaper shower/gender reveal with third baby?

Hi there! I’m 18 weeks pregnant with my third. I have two daughters already who are 8 and 4. I don’t want to have another traditional baby shower, but I’m considering if it’s appropriate to have a gender reveal party with family and close friends at our house. I would not require or ask for gifts, but if someone asked I could just tell them I’m registered on Amazon or we’d gladly accept diapers. Would you do this or think it’s normal? I feel every baby deserves to be celebrated but I don’t want it to seem like I’m asking for gifts again!
