Bear in mind that we want to move hurricanes, not create them. I thought that a large low pressure zone was part of how hurricanes are created.
Blocking the sunlight over a large region (and I don't know how large a region you'd need to block, mind you) would create a cold air mass. I think whether a low pressure zone results depends on the temperature of the other nearby air masses. So that would be a constraint on where you could move the hurricane.
