I came with this crossover... and I quite love it!
Trixie flies a helicopter(Sometimes airplanes in episode 2 "The Great Plan") I also decided that she should be a Pegasus.
RIP Peter Fernandez. He's the one who voiced Speed Racer and Racer X. He passed away on July 15, 2010 at age 83. He grew up living in New York City, the same town I'm living in. Corinne Orr who voiced Trixie is still alive today living in New York City for 4 decades. It's sad because most of the Speed Racer cast are gone.
