It is absolutely not that simple. Even a passing knowledge of heat pump technology as actually implemented would dispel that simplistic idea.
For example, one of the biggest issues to contend with is condensation. Making your outside fan unit cold instead of hot will quickly destroy it due to moisture accumulating in ways that were not expected.

If you lose power for a long time when it has been very cold the system has to be very careful when it starts back up, using the resistive heater to warm the refrigerant and coils to make sure they have not frozen up. But this is all software and is a solved problem.
