Naming one son after another silly?

Kay

Hi my only son is called James he's 10, I have 4 girls and 1 bonus girl, currently pregnant but not finding out the gender. My son has been desperate for a brother, my question is would it be weird or silly to use his name James as a middle name if this baby is a boy? The name we like is Lucas, so it would be Lucas James. Thanks in advance 😊
