So, I'm debating making a second character...

I've been playing around with an idea similar to Snow's.
He made the President Snow, but back in the day, and I was contemplating doing something similar, but a non-canon character.
I was really drawn to Cinna in the novels, hence my current character, Narcissa's, aspiration to be a Stylist. I was toying with the idea of making Cinna's mother, but wanted sound that off on you guys first, before I make her.
(And if you could give me some advice on a portrayer for her, Cinna's being portrayed in the films by Lenny Kravitz.)
(Also, no last name is given for Cinna...any ideas on a last name would be lovely as well!)

Thanks for reading, guys! I'd appreciate some feedback on this, even the negative kind.
