Is this weird

I have two boys. With my first son we had both girl and boy names picked out. I really liked two girl names. Obv we found out he was a boy so we went with a boy name.

With my second son we didn’t have any girl names picked out. We are now

Pregnant with the third and it’s a girl, would it be weird to go with one of the names we wanted to name our first son if he was a girl ? Has anyone ever done this ? I know people will probably say do what you want but I always remember my mom telling me the names that she always went with so I’m not sure if it was personal to that pregnancy or what. Just wondering if we should pick something totally new
