Question / Help Using a dedicated streaming PC when many elements of a scene from the capture PC

This is a fairly complex problem -- hear me out.

PC #1 is a professional audio machine running Pro Tools HD Native (the single audio source) and various music windows (virtual keyboard window, desktop display of DAW [the multiple video sources]).

PC #2 (if I buy it) will be a high-end machine for OBS streaming / recording

PC #2 needs to receive both video and audio from PC #1. A nice solution is HDMI-out from PC #1 to capture card-in on PC #2. Great, easy.

What's challenging is that the final stream (at PC #2) wants to arrange elements that only PC #1 "knows about". Said otherwise, it wants to arrange the music windows from PC #1 in a scene. For example, the scene would contain these elements from the first PC: 1) a window display of a virtual piano keyboard that lights up when the real keyboard is played; 2) a camera feed of the real piano; 3) a camera feed of the player's upper body; 4) a display/monitor of the desktop; 5) some basic artwork.

An obvious answer is to lay out the items on a desktop on PC #1 that will fork into the capture card. But then I lose the great features of OBS, like multiple scene transitions, resizing/snapping views, displaying a virtual window while the window is not actually displaying in the desktop foreground, etc.

Is it possible to have OBS create (or render into-) a "virtual" desktop or HDMI container so that I can send the full final video scene out to PC #2 for rendering? Would that defeat the purpose of the secondary streaming PC?

To summarize, I want to offload as much work as possible from PC #1 because it's main job is professional high-performance real time audio. To do that I considered a second streaming machine PC #2. Unfortunately, PC #1 has stream entities that PC #2 wants to arrange into scenes.

Thanks for your help
