Doom/Firefly plotbunny.. to write or not to write...

So, while I'm awaiting my betaluv for Handle ID Angel (which I suppose I should actually post here huh? lol) I had a really large really hungry bunny start nibbling my ankles about this Doom/Firefly cross and it TOTALLY makes sense in my head.. I was just curious to see if my few buddies over here think it's work writing on...

Basically, a mysterious dark haired doctor is determined to keep his brilliant, but unstable sister safe from a shadowy scientific corporation by catching a ride on the Firefly class ship known as Serenity. 

Poor John thinks some things never change.

So whatcha think? Obviously we'd have to lose the Tam twins (I still luv ya Summer!!) but I can definitely see inserting John and Sam into their roles being a mind trip and a half.

Let me know if I should start writing!
