Yes, I resemble that remark, sorta (...a continent of guys out there that think a vintage plane should stay original). I went the 'resto-mod' route and did it the way I would have wanted Mooney to do it back in the day.
I thought you had to stay to the original part and it's components; i.e., the light projectors, rheostats, weird air vents, etc. Frankly, I just liked "updating" mine with paint and crack repair.
If you plan to go whole hog, then go for the eyeball vents and LED lamps. Also, lose the speaker. Frankly, if you do all that you may get into 'issues' later. When I saw this post I just assumed (yeah, I know) you were just wanting to carbon fiber the existing panel.
As for the Cougar--you dog! I had one back in HS...those were the days.
