Aileron/Elevator Rudder Droop at the Gate

Hi all, bit of a silly suggestion.

But in real life, I notice that the 747-8 and the A320’s Elevation Rudders and Ailerons/Flaperons “Droop” downward at the gate when Hydraulics are depressurised.

Wouldn’t it be a nice idea to incorporate this into the sim to make it much more realistic?!
