It would be an interesting exercise.
According to the Gobi install instructions, the rack itself mounts onto the tracks that also mount the crossbars (if your vehicle is so equipped).
What you would end up doing is this:
1) Mount either a Yakima or Thule rack system on your H1. For more information on how to do that, visit this site:

2) Unbolt the Gobi rack's feet that go into the roof tracks.
3) Install or bolt a Yakima basket or Thule basket locking bracket (sold at bike stores as parts) onto the Gobi rack, and then onto the Yakima or Thule.
