Why wouldn't I want to do that? Other than maybe weight.

It will flex. Rigid = better. The signboard with the CLD is plenty stiff so that there is not a lot of flex. Most of the audio guys would use plywood to plug these holes, the signboard is a much lighter weight alternative and provides about 80% of the rigidity at a fraction of the weight. What you are trying to do is concentrate the area that is flexing and creating sound waves to the driver itself to focus things, otherwise you'll be getting reflections added from the flexing sheet of CLD.
I guess the argument is that since the doors aren't truly sealed, will this make a difference? Maybe not, but I do know how big of an improvement the whole package was on cleaning up the stock stereo especially the bass. Before the door speakers were so indistinct and muddy due to the reflections, now they are very focused and clear.
Feel free to give it a try and see if you still have good results.
