Gimli ringbearer?

Can anyone tell me why it wouldn't have been wiser to give Gimli the One Ring to bear to Mordor if dwarves are so highly resistent to its dark ways? As far as I know, the only effect it could have had on him was to increase his desire for gold, so unless he was in danger of going on an impromptu gold-panning on the way to Mordor, he seems ideal to be the one to physically handle the ring.
