Is This Inappropriate/Weird/Disrespectful? (Please read description)

𝓒𝓪
PLEASE READ: My father died in January of 2017. He was my best friend, my rock & my favorite person in the world. In April of 2017 I found out that I'm pregnant, I'm due December 28, 2017. I would like to include my father somehow in pictures with my baby. I know it would mean a lot to him (& it means a lot to me) to include him in the pictures. He loves his older 4 grandchildren with all of his heart & loved when we took updated pictures with him & the kids. But, since he passed away & no longer here in person I want to have at least one picture with my baby once (s)he is born with my fathers urn. My question is would it be inappropriate, weird or disrespectful to do so?
