Could this potentially be implemented as a "scenario" as described in CameraView frame processing support #1687 here?
I too am looking at ways to achieve this. I have an android implementation already based upon the older camera APIs, but would like to look at updating that to the new APIs before the older ones are removed altogether.

I would like to be able to support scenarios like yours. I believe Android is setup well to support it. I am not convinced iOS is though. I don't want to rush this implementation though so adding scenarios like this is great 👍
