Help choosing boys name!

Okay so my OH and I have two names that we just can’t pick between so we thought of using them both. One as a first and one as a middle, but the only issue is, i’ve already promised my dad that i would use my Grandad’s dad’s name as the baby’s middle name. Does it sound weird? Lorenzo Roman Lazarus D. My OH’s surname begins with D. We were going to use Roman as the first name but it sounded weird having two middle names beginning with L so we swapped it round. I love all three names but just not sure they sound right all together? Honestly i’m torn as its not often his full name will be used anyway 🤷🏻‍♀️ We are honestly the most indecisive couple ever and just looking for others opinions!
