Are these too close?

Name Advice
1

So I love the name [name]Viola[/name] with an occasional nickname of [name]Lola[/name]. I also love the name [name]Luna[/name] and every once and a while call her [name]Lulu[/name]. Are [name]Lola[/name] and [name]Luna[/name] too close? What about [name]Lola[/name] and [name]Lulu[/name]?

I do think [name]Lola[/name] and [name]Lulu[/name] are too close.

[name]Viola[/name] and [name]Luna[/name]? [name]Love[/name] them together.
[name]Lola[/name] and [name]Luna[/name]? Matchy but not too close.
[name]Lola[/name] and [name]Lulu[/name]? Too close.

But I think if [name]Viola[/name] and [name]Luna[/name] were their given names then you’d be okay.
