I'm currently in the middle of building a 1999 35th anniversary edition. Ford mustang with a bored and stroked 351 to 427 cu in with 850 hp and 2 stage nitrous to boot.
Good Luck if you decide to do it. I'm not sure which other MB's use the 6 speed, I'm not even sure any of the US or UK V8's do. The block is basically the same as the V6 so it should mate up OK as long as the input shaft/flywheel setup is similar.
I think bolting in the V8 lump and mating it to the trans, then fabbing up the exhaust and ancillary mounts etc. is the 'easy' bit. The fun will start when you try and get the rest of the car to be happy when you pull the ECU and other modules. Even assuming you completely transplant the electrics from the V8 you may get problems with the rest of the integrated CAN systems scattered around the car. Just ask HDDP what happens when you start disconnecting things.
You could just rip the whole lot out and make up a new loom and go for a custom management system. But its all time and money. It also depends on what you are trying to achieve - a sophisticated and refined road car with a 'factory' feel, or a no compromise racer. The latter is easier, the former is very difficult indeed.
I would relish the challenge but I just don't have the time or financial resources to contemplate it. So I wish you the Best of Luck if you go ahead.
