Depends upon what they are really trying to do, and how they want to structure it, coupled with how much they want to spend. They could, for example, have an enhanced safe harbor match of, say, 200%, or even more, of the first 6%. Something like that would, to me, seem like a pretty powerful incentive. But it might not suit the employer's needs/budget. A cross tested PS formula, depending upon census, can work wonders, although in this case, a nonelective safe harbor (regular or enhanced) might be a better option, as the safe harbor nonelective can be used toward satisfying Gateway, whereas the SH match cannot.
