Can't hurt as long as the panels still fit Might be a good chance to add a switch for the lighting so it can be switched from the bunk.
I ended up going with a similar bubble foil insulation. It's sold at both Home Depot and Lowes. I was going with fiberglass at first but the bats are heavier and i was concerned they would droop from the cap adding more weight to the ceiling panel - which already has the tendency to droop between the anchoring screws.
It's time consuming and tedious but I can tell a difference in the areas added. I went with 3 layers since in some of the pocket spaces, that's the thickest you can fit.
In regards to the light, I assume you are referring to the LED strip at the nose. That power wire runs along entrance side of the coach all the way to the front. When the side soft-touch panels are removed you can easily reach this wire without removal of the ABS ceiling panel. However, if you are going to add insulation, well the ceiling has to come down anyway.
