I don't see how choosing the static route is an experiment, vs
installing a fan. The basics of static venting are well understood.
And whether they have a gable mounted fan or static venting, half of
the project is similar. They need sufficient air intake, preferably
at the soffits. From the description given, it;s not clear that this
exists. In fact, with a powerful fan, they would need even more
intake venting, making that project more work.
Also, I think adding a ridge vent in most cases is no harder and
perhaps easier than adding a gable vent.
