Naming help for a boy

My husband had a friend who passed away and he wants to honor him by naming our son after him in some way. Originally, our plan was to name our son Julian Isaiah, but now we are trying to come up with a way to include his friend's name into our son's name, without making it too long.
His friend's name was William Lee Gray. 
I'm not crazy about the name William, and my husband doesn't like the name Grayson. Does anyone have any other suggestions on how we may be able to include his friend's name into our name?
