Using FrSky Passthrough instead of MAVLink?

Is it possible for a transmitter to send data to the FC using FrSky Passthrough ? SmartPort is bidirectional, right ?

There is bi-directional Frsky telemetry in the works by Alex Apostoli, creator of Yaapu Lua script telemetry. It essentially puts a GCS on the Frsky Transmitter. Info:

Frsky bidirectional telemetry implementation

The way you describe it makes it sound easy! (I was just being humorous…)
