Alternatives to Dylan?

Since I was about 14 I have always wanted a little boy with the name [name_m]Benjamin[/name_m] [name_u]Dylan[/name_u]. Problem is, partners surname is [name_m]Duncan[/name_m]. Although I like how [name_m]Benjamin[/name_m] [name_u]Dylan[/name_u] [name_m]Duncan[/name_m] sounds… I’m also not overly happy about it, and partner likes it even less.

We took [name_m]Benjamin[/name_m] [name_u]Dylan[/name_u] off the list… but I’m so attached to it, I keep putting it back on. Are there any other middle names that may work. Names we’ve agreed on in the past:

[name_m]Cove[/name_m]
[name_m]Fox[/name_m]
[name_m]Lochlan[/name_m]
[name_u]Everest[/name_u]
[name_m]Atlas[/name_m]
[name_u]Avery[/name_u]
[name_m]Griffin[/name_m]
[name_m]Boyd[/name_m]
[name_m]Ezra[/name_m]
[name_m]Shepard[/name_m]

I think the below would work with your surname
[name_u]Arden[/name_u]
[name_m]Caleb[/name_m]
[name_m]Callan[/name_m]
[name_m]Elijah[/name_m] / [name_m]Eli[/name_m] / [name_u]Elias[/name_u]
[name_m]Damon[/name_m]
[name_m]Frederick[/name_m]
[name_m]George[/name_m]
[name_u]James[/name_u]
[name_u]Kieron[/name_u]
[name_m]Landon[/name_m]
[name_m]Lewis[/name_m]
[name_m]Matthew[/name_m]
[name_m]Nolan[/name_m]
[name_m]Nathaniel[/name_m]
[name_m]Oscar[/name_m]
[name_m]Wolf[/name_m]
[name_m]Zach[/name_m] / [name_m]Zachary[/name_m]

I have a cousin [name_u]Dylan[/name_u] with a brother named [name_m]Colin[/name_m], which is similar in feel. Or maybe something like:

[name_m]Callum[/name_m]
[name_u]Chase[/name_u]
[name_u]Emmet[/name_u]
[name_u]Finn[/name_u]
[name_m]Forest[/name_m]
[name_m]Gavin[/name_m]
[name_m]Kellan[/name_m]
[name_m]Lincoln[/name_m]
[name_m]Ramsay[/name_m]
[name_u]Reid[/name_u]
[name_u]Rhys[/name_u]
[name_m]Roman[/name_m]
[name_m]Stellan[/name_m]
[name_u]Tristan[/name_u]
