I'd move the daytime AM stations first, so that they could guide their listeners at the nightly sign-off to tune to the new FM frequency to continue listening. In 6-18 months, retire the frequency. If these stations want to simulcast 24/7 during the transition period, that would be their option.
Next, move the full-time AM stations, who would be the only ones truly burdened with a 24/7 simulcast.
Third, if any space remains, allow an LPFM licensed for less than 100 watts (although personally I'd raise the LPFM ceiling to 250 watts) to move to a new frequency if they so desire.
Once all AM stations are retired, rewrite the rules regarding changes to stations' community of licenses to reflect that stations really don't serve suburbs, but metro areas-a lot of smaller FM stations could be replaced by fewer, larger FM allotments that cover the same number of folks (i.e simulcast partners 104.3 WAYI and 105.9 WRVI become one station by consolidating into a single frequency in Louisville).
