If incumbent protection comes into play, than one demand may be a "triangle" seat in Central PA that protects PA06. It's probably the safest seat for the region that makes both geographic sense and keeps the rest of the regional preferences intact. It all depends upon what happens in 2020 of course.
The triangle seat is interesting, what are the election #s on that?
Also, I wonder if it might be possible to similarly have a Harrisburg-Reading-Lancaster triangle seat (alternatively to the more obvious possibility of a Harrisburg-York-Lancaster triangle seat, which IIRC there is probably not quite population for).
