How to combine the two...

Paige
So, my bf and I are having a little boy 💙🤰 We want to name him after his father who passed but also after my brother. BF doesn't want 2 middle names. His dad's name is William and my brother is Lee. So I've been thinking of ways to combine the two. We like the name Liam but bf wants to spell it Liem which I still like. But curious if there is any other way to combine the names. TIA
