Yes it would be a superb addition....also on fleets.
The tactical considerations are well thought out IMHO.
I Like the ack tracking.
I Like the slave SL's increasing white out.
Some thoughts
Light blinding should be easily triggered by the TPOV looking straight at the beam source when in the cone.
The cabin could be brightly illuminated by the existing system that illuminates it from the sun......but brighter when in the cone.
A pilot in the cone but not suffering from light blindness should still be able to see out of it.
The cone.....why is it visible? In practice its visibility is down to how "dirty" the air is. Dust, water vapour, smog etc.
If we assumed AH world is pollution free then worrying about cone graphics could be dismissed except when under rain clouds or shining at cloud bases or local mountains.
If not and a visible cone is considered more representative (morning dew?)(and threatening), at what range would the cone be visible from RPOV?
I think that the more visible the cone the harder it is (from a distance)to see any thing illuminated by it due to cone "glare". Hence a dirty cone (highly visible) is harder to see out of and into.
Would the SPOV need to see his cone at all? Would not a red cross hair showing the direction he is pointing be sufficient? (unless illuminating a cloud or mountain)
An aircraft lit by an SL would then simply light up (even better if icons were very short range at night and simply went long range when lit by an SL)from the SPOV point of view or any RPOV able to see the lit part of the aircraft.
An RPOV above the TPOV (out of the cone)may not see anything except the bright light source.
