I like the sound of [name_m]Davis[/name_m] [name_u]Carlyle[/name_u] and [name_m]Lucas[/name_m] [name_u]Carlyle[/name_u], as well as [name_m]Lucas[/name_m] [name_m]Haynes[/name_m]. If you’re open to [name_u]Carlyle[/name_u] as a first name, I’ll also suggest [name_u]Carlyle[/name_u] [name_m]Davis[/name_m] (or [name_u]Douglas[/name_u] or [name_m]Smith[/name_m]). 
With the exception of [name_u]Douglas[/name_u], I’m not a big fan of [name_m]Luke[/name_m] with most of your middle name picks. [name_m]Luke[/name_m] [name_m]Smith[/name_m], [name_m]Luke[/name_m] [name_m]Haynes[/name_m], [name_m]Luke[/name_m] [name_u]Carlyle[/name_u]… they sound choppy to my ear. I feel like I have to pause between saying the two names.
That being said, first/middle combinations aren’t as important as first/last combinations. [name_m]John[/name_m] [name_m]Alexander[/name_m] [name_m]Johnson[/name_m] is still [name_m]John[/name_m] [name_m]Johnson[/name_m] in his day-to-day life. So if you find a first name you like more than any others, I’d tell you to go with it, even if it doesn’t sound perfect with the middle name.
I voted [name_m]Luke[/name_m] [name_u]Douglas[/name_u] because I like the sound of [name_m]Brooks[/name_m] and [name_m]Luke[/name_m] as brothers.
I voted [name_m]Lucas[/name_m] [name_m]Smith[/name_m] because I like [name_m]Lucas[/name_m] as a first name best. I also like [name_m]Lucas[/name_m] [name_u]Carlyle[/name_u] or [name_u]Carlyle[/name_u] [name_m]Luke[/name_m] as options.
Good luck.
I really hope you consider [name_u]Carlisle[/name_u] as a first name since it’s one of my favorites! [name_u]Carlisle[/name_u] [name_u]Douglas[/name_u] is handsome.
I do love [name_m]Lucas[/name_m] more than [name_m]Luke[/name_m] and [name_m]Davis[/name_m] is fantastic. You are very lucky to have such usable family names.
I like these combinations in this order…
[name_m]Brooks[/name_m] [name_m]Paul[/name_m] and [name_m]Davis[/name_m] [name_u]Carlyle[/name_u]… [name_m]Brooks[/name_m] and [name_m]Davis[/name_m]
[name_m]Brooks[/name_m] [name_m]Paul[/name_m] and [name_u]Carlyle[/name_u] [name_m]Davis[/name_m]… [name_m]Brooks[/name_m] and [name_u]Lyle[/name_u]
[name_m]Brooks[/name_m] [name_m]Paul[/name_m] and [name_m]Lucas[/name_m] [name_m]Haynes[/name_m]… [name_m]Brooks[/name_m] and [name_m]Luke[/name_m]
I like [name_m]Davis[/name_m] [name_m]Haynes[/name_m]
[name_m]Luke[/name_m] [name_m]Davis[/name_m] or [name_m]Davis[/name_m] [name_m]Haynes[/name_m]. I think [name_m]Luke[/name_m] [name_m]Davis[/name_m] sounds best but [name_m]Davis[/name_m] as a first name, goes best with [name_m]Brooks[/name_m] ([name_u]Love[/name_u] his name too!)
