Hi Tom,
When I bought my XLR, one of its previous owners had plastered absolutely every interior panel you could think of with woodgrain shtuff.

It was like driving a log cabin!
Hours and hours of fake wood removal sort of explained to me just why: lots of little dents in the beer-can thin aluminum overlay. I decided to go for carbon and took it a step further and peeled all the aluminum off...and it's not easy at all and is destructive (i.e. there's no going back).
What you're left with is black plastic and it will be flawed enough that you need to address some mold marks and such with spot putty prior to applying any wrap.
Vvivid Vinyl
--Vvivid Link-- has an interior grade wrap that's outstanding. I'm an amateur with 'wrapping', having used regular wrap (or tried to), and the interior stuff was just great to work with. I did try their exterior vinyl first as I had some from a previous project and it was just too difficult. That might just be me though.
The biggest headache if you follow this path is around the shift indicator (just to the left of the shifter). Without the aluminum in place, you have nothing, so you'd need to plan to either carefully cut out that section of the aluminum and wrap it as a separate, or fidget something together... in any event, I'd suggest to study what you might do with that area before anything else.
As a part of that project, I swapped out the shifter for some other Cadillac model so it's now just all black leather, found a 'plain' XLR steering wheel (no wood ~ all leather), removed the aluminum on the wheel and carboned that, along with the aluminum on the door panels. That vinyl is even flexible enough to go in and over those fake sticks of wood they've used for the door handles (use heat and be patient). Ditto with the cupholder / ashtray cover and the blank panel beside.
It's a long and trying job - well, it was for me. Results thus far are lovely (imho) and I'm even considering a bit of a console modification something on the lines of pitching most of the stereo and quasi-useless CD player, and reworking in some gauges seeing as the vertical section of the console is sort of blah and like you, I am considering a different radio though probably a single DIN.
Hope that helps at least a little.
Gord
