Yes, that would work well for the operations right enough will have to start using features.
It wouldn't work for the stock dimensions, colour and transparency though. It also wouldn't help with such things as the rectangular surface plane defaulting to metric equiv of 2" x 2" x 1/2" rads etc. All not really a huge deal as mentioned but a bit annoying that you have to change every time you use.
Regarding Machs wizards, well to me they are very basic and not much use unless you are simply wanting to just do a quick reduction in dia or enlarge a bore or similar. Also the standard ones have a few niggles such as the finish pass amount also determines the amount left on Z when roughing, not a great idea when you have an extra 1mm on the Z that the finishing tool tries to remove. I altered a couple of the wizards so I have options to set the Z finish amount and also altered it to have the possibility of selecting a different tool for finish and roughing.
To be honest though I hardly ever use the wizards, its often just as quick to MDI if it is a simple job and definitely much quicker to do anything slightly more complex in BobCAD than do lots of separate operations in the wizards or cut/paste wizard code to produce a finished part.
