Anyway, I am wondering about those power flush toilets because it uses
even less than 1.6 GPF (1.0 or 1.4 GPF) so I am not convinced it will help
me. The pressure toilets look appealing however.

We had a similar problem at work with a 50' horizontal run. It needs a lot
of water so the solids can float away. A pressure toilet helped. One
advantage was that fact that it had a quick recovery. You can flush half way
through your business, again when you are done, again when you use the
paper. That took care of most of the problem.

Fast forward a few years and add a second toilet. Only difference this time
is venting. The first setup was a hack job and not properly vented. The
addition was a good plumber and he added a vent, put in a standard style
toilet and there has not been a problem in a year of use.

One ore thing. Have the ladies dispose of those cotton things in the trash
instead of a flush. The maintenance guy knew when the secretary had her
period by when the line plugged up.
