Naming my baby (if a boy) after my dad &&' uncle but want to throw in an extra name. I'll let you help me decide!

My uncle passed away a few yrs ago on the 4th of july of a heart attack in our bathroom and my father passed away due to complications of pneumonia this yr On Feb. 4th. My father was wanting to name their son (they were ttc for several years) John Michael but due to his passing we decided to take up the name. John is for his name Johnny and Michael was his brothers name (my uncle) I love the fact that I'm doing this but i really want to add colson into the mix. What do you all think? Our last name is Italian so it actually works well with both!
