Not sure about Orlando, but IMHO over seeding a SA lawn with northern grasses is a bad idea down here. We have several properties where the HO's over seeded with rye. It grows at a different rate than SA. It can outgrow the SA so the lawns look shaggy, sometimes it grows so fast it goes to seed. When it's cut, seed is distributed throughout the lawn and has a tendency to come back up in cooler areas all summer long. It's a PIA, like Bermuda in SA or Zoyesa in SA.
At best it's a temporary fix. The SA lawn will look sickly when the grass transitions back to a more robust SA in the spring, and if the SA was sickly when you started, it'll still be sickly after it transitions.
Best to build and maintain a healthy & robust SA lawn incorporating a professional IPM program.
