That would be an amazing spectacle (and the Force Unleashed fan in me is giddy at the prospect of destroying more Star Destroyers with Force Pull), but I don't think even a SSD's impact on a moon-sized space station would destroy it - I prefer Lando taking out the core. You could try having the SSD crash simply overload the Death Star's shield, but then there's the problem of conveying on-screen (in both a logical and thematically-satisfying way) how Han destroying the shield generator somehow didn't destroy all of the shield.

It's a cool idea, and part of me really wants it to work - but I just don't see it fitting.
