Correct. mincreshape does no volume averaging/blurring/interpolating
that I know of. In this case mincresample is what you want. This sort
of doubling/halving of step sizes is voered by autocrop with the
-isostep style options. Because I like making my own toys I have a few
incarnations of this here:

I see Vlad has also responded with his own tool to do this.
