It would be not just cool to look at but also very helpful if the stock quality would be quite a bit better. Especially if your model has got surfaces with a radius like a fillet or so. I'm facing situations where I cannot see if the toolpath is bad or just the simulation. Here are two examples:
Vertical wall fillet:


See the problem at the upper chamfered area above the red arrow? Bad tool path or bad stock simulation?
Here's another example:


So, what is the problem? The tool path or just the simulation?
Personally I think it should be possible to define the grade of quality by our own. By that one with a strong machine, a high end PC could benefit from it and have a very accurate and high quality simulation whereas one with not such a strong PC could still run the simulation fluid.
