Not opposed to the idea at all as long as it is dim enough to to not interfere with night vision.
For my illuminated center channel I just reused a cup holder led module.

The issue I see with it is that you will need to space out or trim back the trim to provide an area for the light to shine thru/on like the radio does. I’d probably try using a semi opaque white plastic as a light strip and standard 1206 cool white and amber leds.
That’s what my illuminated b pillars have in them.

Best of luck.
