Opal nn Polly???

What do you think about using the nickname [name]Polly[/name] for [name]Opal[/name]?
It would most likely just be used by close family and friends.

I think that using [name]Polly[/name] as a nn would cheapen [name]Opal[/name].

I have this on my long list with the nn [name]Polly[/name]. I also have [name]Opaline[/name] with the nn [name]Polly[/name] too. I think it is niceā€¦
