Super Nintendo AV connector for Video Game Shield

Hi would a redesign of the Arduino Video Game Shield be in order if it could eliminate all three RCA connectors from the board? I see the design already uses the Nintendo PCB card edge connectors for the controllers, what about doing the same thing for the Video and sound outputs? the Super Nintendo AV connector can be implemented using a card edge connector too. this connector also opens the door for experimenting with S-Video and perhaps even some colors.
