Is the Grand Hyatt so bad? You have elevators directly from the the platforms of the Hibiya line to the station concourse, then along the tunnel toward the 1c exit for Roppongi Hills. There's an elevator in the Metro Hat which goes to the Roku Roku Plaza, from there you go into the West Walk and catch an elevator up to one of the levels which has the bridge to Grand Hyatt.
It wouldn't have thought it was significantly worse than the walking route; as I play it through in my head. I might be missing something significant though, as I've never actually tried it in a wheelchair.
