Would this be wrong?

I found out the gender today through my blood results. It’s a boy!!!!

My husband REALLY wants a boy. I mean to the point that he buys boy clothes and tells me everything he’s going to do with the baby. We have 2 little girls. One who passed away last year.

Would it be wrong to do a funny gender reveal and make him think it’s a girl then surprise him with the blue?

I thought it would be funny because he keeps saying “I know it’s a girl. But I want a boy”
