THE BIG BANG THEORY Re-imagined as FIREFLY by Artist Megan Levens

I saw Megan Levens' drawing (cropped and resized below) on Zap2it.com:

I think the characters would match better with Leonard as Mal, Raj as Simon, Penny as Inara, and Amy as River. The rest of Megan's casting works for me.

Taken with the drawing, I clicked over to a video interview of Megan, who's also known for the web comic Somewhere in Between.
