Laura Vandervoort in Supergirl?

I do not have a thing against Melissa Benoist who plays Supergirl on the CBS series.
I think she is great.
But you have to give props to Laura Vandervoort (SyFy’s werewolf drama Bitten), was the original live action Supergirl on CW’s Smallville.
I know there are a few rumors that have floated around about Laura maybe showing up on Supergirl at some point which I think would be great.
But they are really nothing more than rumors.
Though they did cast Helen Slater (the movie Supergirl) and Dean Cain (Lois and Clark) in roles....
So you never know.
Who could she play?
I like the idea of her crossing over from Earth 2 as Powergirl.

Anyway, here is the beautiful Laura who had to play Supergirl without ever really getting a costume.....
