Alternate "Powered by Unity" Splash Screen?

Is there any way in a personal edition license to create an alternate “Powered by Unity” splash screen (to be approved by Unity of course) that better fits our game’s style? So instead of the default splash could we create a different screen with the unity logo that says “Powered by Unity” similar to how “Powered by 4A Engine” appears in the Metro Last Light Menu intro

As far as i know unity does not offer any other kind of splash screen option for the personal edition license.
