It seems that all the suggested ideas have no effect.

Seems like FDISTRIB should be helpful here in some way. Perhaps in combination with flag settings and/or other steps? I've also noticed that in certain situations EXPAN seems to give more intuitive results than EXPAND, though I don't know the details of its process. It may be worth some experimentation as well.
