Thoughts on your list:
[name_f]Eleanor[/name_f] → elegant, lovely and has great nn potential! I think it sounds fine with [name_u]Florence[/name_u], though saying them together, [name_u]Florence[/name_u] and [name_f]Eleanor[/name_f] sounds a bit better than [name_f]Eleanor[/name_f] and [name_u]Florence[/name_u]
[name_u]Evelyn[/name_u] → sleek and sharp and matches well, but if you feel it’s too close to your name, it might not be the one
[name_u]Hazel[/name_u] → warm, earthy and sweet. I really like it with the set
[name_f]Josephine[/name_f] → charming, strong, literary and elegant - works with the set
[name_u]Rose[/name_u] → I think both are so established as names, that it works fine for me!
[name_m]Atticus[/name_m] → I don’t think it’s too out there - depending on where you are, [name_u]Florence[/name_u] is even lower on the charts than [name_m]Atticus[/name_m] It fits really well with [name_u]Wesley[/name_u]!
[name_u]August[/name_u] → charming, warm and lovely, vintage but fresh!
