The return line on the W140 is pretty tough to get to, nothing like earlier models where it's right out there with a hose clamp on it. I don't have any Stoddard solvent, but I do have two liters of MB PS fluid, so I have plenty to flush.
I'm not keen about the turkey baster/suck the reservoir dry/refill/repeat approach, as I think it's horribly inefficient and won't get all of the old fluid out. I would be a lot more comfortable with a drain and refill at least. I have some things to take care of in the morning, then I'll get it up on jack stands and have a closer look. If I can remove the centering bolt and use that to drain the system I would be happy with that....
