I think there is supposed to be a disgustingly fast AMG Mercedes with a turbo diesel in it, but can't remember what it is called. As for a Turbo Diesel G body, you have to look at donor vehicles other than large trucks for a suitable one. BMW, Mercedes and Volvo all produce Diesel cars either in the US market, or for the European market, many of which are RWD ( MB and BMW have never built a FWD car). Diesel comprises around 50% of the new vehicle market in Europe unlike here where very few diesel cars are sold. As for GM's Duramax, it is not a GM USA design. It was designed and built by Japan's Isuzu which GM has a big stake in.
As for my own diesel aspirations, my timeline may have to get a little more urgent. It seems the redline powershifts I do to it all the time may not have sat well with the rod bearings in my Frontier. It still runs fine but is starting to sound like a diesel when it runs. So, I am now hoping it holds out long enough for me to save the $500-1500 it will cost me to get a replacement car( preferably a 300TD wagon). I can't just fix it as it would take time away from my job. I deliver pizza as my only job and can't work without it.
