Wonder if you can retrofit a Taycan dash and do your own squishy bits (software)?

Trying to replicate the original dash in glass is one thing. For anything else, it could be a lot worse than analogue if you don't get the X in "UX" spot on.
My A class has the latest "MBUX" with digital dash. I wasn't sure if I would like it, but now when I get into a normal car, it feels like using a flip phone. I'm short so not having a dash hump in the sight line is a bonus (the classic 911 dash is actually really good in this regard too). One thing I find amusing is that if you get into a higher class MB now, you see the exact same dash. Good if you're an A class owner, perhaps less so if you own an S class (although I think the new S is getting the next gen MBUX). I guess this kind of "shared design language" always existed across the model range of MB/BMW cars, but now the class differences are not so obvious.
Do you run a screen with your Raspberry Pi setup? What model is it? I tried the original Model B as a streaming box but wasn't quite cutting it. Debating between a 4 or newer Pi or just going with a proper USFF.
In a sense, moderns cars with CAN bus might make things easier. For one, there is a lot of data already available through the OBD output. Obviously, with analogue cars it's a different challenge but a fun one
