Can a submersible pump and manual pitcher pump coexist?

With a typical 1 7/8" working barrel, each foot of water column lifted

That's before any mechanical leverage applied at the handle. Also, the
piston diameter might not be the same as the pipe diameter - the max
size depends on the well casing. The force depends on piston diameter,
not water column diameter.
But no matter how you arrange the mechanism, lifting a certain volume of
water 150 feet will require at least 5 times the mechanical work
required to lift the same volume 30 feet. That was my point.
