I like Kerry's idea, but instead of just removing the Union bus station - we can keep it's facade and let the other urban development incorporate it.

I also disagree that we need the hub to be in the current CBD area.. There's no reason why the hub couldn't be in C2S somewhere, with the streetcar connecting it to the rest of downtown. After all, isn't the goal of this whole thing to get people using mass transit and AWAY from cars/busses/etc? Well, having the hub near the convention center ON the streetcar line accomplishes that and many many more.

And I completely agree that the current bus hub in midtown should become greyhound (but also be on the streetcar line). I think it would also be a good idea to have a car rental or two there or at Amtrak (like it used to be). The C2S main hub could be Commmuter Rail/HSR/light rail/streetcar/city bus intermodal facility (in other words, I don't think greyhound needs to be there).
