Hi Tomasz,
Great thoughts on the 3-D suppression implementation. I have to admit: 3-D suppression is really challenging. If you implemented your suggestions, would you please share your code (or link to your code)?
As for the optimization, you are correct - the results will depend on the data composition, the order of suppressed variables and, of course, selected optimization criteria.
Another, and perhaps the simplest, approach could be splitting 3-D report into several 2-D reports, that is using subsets of the data for each value of the third dimension. In this case, one can apply 2-D approach described in this post.
