Our 140 is coming up on 1600 hrs TBO.
I know that some may say sell the plane and buy a 180, but we have a plane
whose condition we know

In a plane like a Cherokee the engine is the number one point of concern- by
the time you've overhauled or done an engine swap you no longer have "a
plane whose condition you know" in one very significant sense. You may,
however, have a warranty, for a few years anyway.

avionics than most and would hate to do the new buy thing and then spend a
lot extra getting the plane's condition up to that of our current one.

Easily avoided: there are guys like you out there selling above-average
PA-28-180s etc. trading up to even bigger faster planes. The higher up the
totem pole you go the more likely you'll find one with the goodies you want.
