Having a "Central Hub" type thing would be great, but it would be a massive undertaking.
Are you talking about playing Vietnam maps on 2142 or
BF2? If so then thats alot to do. Even if you're not talking about that, the redesign of maps to update graphics would be huge just by its self.
I'm not saying that would not be great, it would be awesome, but I'm not holding by breath.
