If they can get everything into MPEG-4 (going from market to market based upon the HD LIL launch) then that would free up space with the SD locals. What they could do is shut off one market at a time and to prevent as many people to becoming affected they could start with the smaller ones in which would free up more space on the satellite. It would not take them as long to switch the smaller markets out and more free space would be acquired and fewer receivers to swap out. This would give the hardware more time to drop in price by the time it made it to the larger markets.
