Stage map mixer idea

It would be practical and intuitive if Musescore had a "stage map" mixer. In other words, a mixer where I could arrange the instruments on a virtual stage (left, right, front, back). So far it is only an imprecise idea that could be refined.
From my point of view it should be an additional mixer and not replace the existing one.

The idea:
There is a map "virtual stage" in the upper area. In this area the instruments are arranged in the middle, or even further right or left, depending on where they should appear in the stereo picture. The panning of the instruments is done as if they were arranged right or left. (An idea for instruments that should appear at the same place is still missing. Overlay?)
Besides an icon in the upper map a small volume bar appears to adjust the volume quickly and easily.
Below the map the instructors are arranged again to make it easy to use the map by keyboard. By double clicking on the instrument (top of the map or bottom of the bar doesn't matter) the setting field for the selected instrument appears. There you can edit all the settings for the instrument, like Midi, Mute Solo, Volume, Name etc. (here you could also integrate Kontakt Player)
Mute instruments are greyed out and solo instruments are red.
If an instrument is selected in the lower bar, you could jump to the same instrument in the 2D map by a key combination in order to move the instrument there with the arrow keys.
A rough preview without details could look like this. More ideas and thoughts?
