If Seven wanted to dare to be different, perhaps part of your schedule would work. People are getting used to Home And Away 2 nights per week. However, what if Seven changed it to screening double episodes Monday And Tuesday from 7:30pm in the same slot occupied by A Country Practice in the 1980s), Wednesday night launch a new situation comedy (noting previous successes - again in the 1980s - Kingswood Country and Hey Dad!) paired with a US Comedy, Thursday could be a new Australian drama (or a revived one - eg The Flying Doctors, Blue Heelers etc).
Reality TV could air at 8:30pm - look for concepts that are edgier.
