Sony may have prevented third party sellers from providing you with replacement face/side plates, but you can do whatever you want to them yourself. This guy wrapped his PS5 in vinyl.
You can see this stunning TVR style Chromaflair paint that disperses light to adjust the colour of the console from different angles.
This vinyl material is fairly inexpensive depending on what you want to use it for, and you may be able to get offcuts from car wrapping places as the PS5 has a lot less surface area.
Would you wrap your PS5 like this? What do you think of the overall design?
