...This is how it would open. Aislinn Trista put together a nice mash-up of the Cowboy Bebop opening theme in a tribute to Shepard's companions. Check it out after the break.
Aislinn clearly has a love for both franchises. She takes care to match the beat of The Seatbelts' "Tank!", even including a sultry Miranda boots-walk in place of Faye's in Cowboy Bebop.
You can find Aislinn's YouTube page here, where she's posted a few additional Mass Effect videos.
Also, a bit of bonus nerd trivia - Steve Blum and Jennifer Hale provided voices in both franchises (Spike Speigel/Grunt and Electra/FemShep, respectively).
