I think the honor name trumps all else and let’s be honest, [name_f]Susan[/name_f] is a great name. 
A more modern/creative nickname could balance any reservations. Years and years ago, I saw [name_u]Henry[/name_u] [name_u]Atlas[/name_u] on here and always thought was a striking balance.
[name_f]Susan[/name_f] [name_u]Lake[/name_u] or [name_f]Susan[/name_f] [name_f]Lyra[/name_f] or [name_f]Susan[/name_f] [name_f]Wildflower[/name_f] or [name_f]Susan[/name_f] [name_f]Noelle[/name_f]?
