TDi badges are just a sticker and easy to get. The engine is not even TDi though. This could be a good setup, my fears are too much engine for the transmission and it would have to be very closely inspected before purchase IMO, and the quality of the conversion of course. The engine definitely looks like a shoe horn as that is a large engine. I am also doubtful that is a Detroit Diesel, I think it is a Chevy 6.5 NA (which works but is also a PITA diesel. These are what came in early-mid Hummers). Naturally aspirated diesels suffer heavily from altitude, and if the engine was overheaded it could have head gasket and other issues. The unique aspect is the body of course, but not sure if it is worth it IMO.
