html_ui in external browser?

[HellGL]

Is there a way to run the html_ui pages (e.g. PFD) in an external browser without MSFS2020 itself?

Background:
I would like to let my custom simulation software drive the displays (PFD, ND, EWD and ECAM) in a home cockpit like environment. I already have the panels implemented as interactive html pages with embedded SVG images converted from a cockpit poster. Connection to the simulator is done via a RabbitMQ server with WebSocket plugin. The simulation is (at the moment) based on X-Plane 11 and the displays in the MIP are Pop-Out windows placed behind the HTML page (transparency feature of the electron web engine). To make the setup more modular I would like to run the panels and the displays on separate computers (e.g. Raspberry Pi). I searched the web for some time and found several glass cockpit software solutions, but none of them runs on Linux, has a flexible back end or has HTML5 based displays where I might add additional display elements if needed. My idea is to implement a websocket client that connects to the RabbitMQ server to receive the necessary data to drive the displays. I already cloned the repository and setup the development environment, but I have no clue open the display html files, as there is apparently some kind of wrapper code () missing to open it in a normal browser. I think if I can run the html files in a browser like electron I will be able to find a way to read the necessary variables from somewhere and translate them into the correct internal variables to make it work.
Any ideas or help is much appreciated!

Thanks,
