Additional functions for helicopters - possible?

Hello,
meanwhile I get along well with Pixhawk 4 mini, Ardupilot and MissionPlanner. I have equipped 5 helicopters with it, 2 of them tandems.
Now I have a few wishes for additional features on the helicopter, if such a thing would be possible.

  1. trimming of the swashplate.
    It would be practical to trim the whole swashplate in height (for hovering), similar to -min, -max and -mid.
    Especially on a tandem you could easily match both swashplates and compensate differences.

  2. tandem pitch control.
    On a real tandem the swashplates make a nodding motion (like on a single helicopter) and move a little bit up or down at the same time. I think -nick- (pitch) becomes a bit more comfortable and softer. And it would be scale-like.
    It would be nice if you could adjust the ratio continuously from 0 - 100.

  3. -standby- on the ground .
    When the helicopter is on the ground and running, it sometimes happens that the tail wants to turn away (from the heading hold). In tandem the rotors become increasingly interlocked. With -standby- you can prevent this.
    I have this with a mixer in the transmitter on the throttle-stick. When it is down, -standby- is active. When I lift it slightly, -standby- goes off.
    Could this be programmed, or any other programming with the same effect?

If something like that would work, that would be great!

Thanks a lot
