This seems like a pretty reasonable study outline to me.
If I had to nitpick, I would suggest simulating data from the interpolation model rather than extracting the results of a single interpolation. This allows you to do multiple repetitions for each gridding, where the data for each repetition comes from the same model and differs only in their random components.
That being said, in Geostatistical Analyst, you can only simulate from univariate Simple Kriging models, so that might not be an option.
I'm definitely interested in the results, I've done some ad hoc experimentation along these lines but not enough to draw any solid conclusions.
