Hey babul : )
The goal is to remove all the friction induced by the 10000 ways of doing presets and control a scene in virtual photography situations inside VAM.
By starting to divide the way you handle lighting from the plugin, you start complicating things and potentially induce bugs OR "ha yeah this time that was a light in a subscene and that time it was a light in my light preset" scenarios.
Also, handling the same feature as Maestro's light rig will imply to have new control. Which will pack the UI with additional controls that only you (or a couple of other persons) will use when the rest will use the integrated light preset system.
You can simply load up your favourite light rig subscene, then save a light preset. I know there's a bug to fix that I will address soon, you need to unparent the items beforehand. But in the future that's gonna be as simple as loading the subscene with your light rig and save the preset.
I think what you're trying to achieve here goes in the opposite direction of the plugin's goal : )
To use an analogy: that's like if you were asking your car dealer to have a stick shift on top of your automatic transmission. That's kind of counter productive, choose one or the other ^^
( and don't tell me that semi-auto cars exists, that's not the point I'm trying to make
)
My way of saying: embrace the lighting process from Maestro and save your favourite light subscenes as Maestro light presets. Subscenes were just a way of compensating the lack of tools. Maestro handles that by itself : )
