Apple Motion 5 Template Customizing

I would like to take the Sports Theme in FCP X and customize it so that I can select my own colors. As it stands this theme is only available in blue. I use this theme with several clients for sports videos that I produce. Since they each play on different teams that have different color uniforms, etc., I would like to be able to have the ability to use this theme in any color scheme that I want. If I like what you do here, I may want to do some additional customizing and/or designing of other templates in Motion 5 for use in FCP X.
