I think it would be very difficult to develop a
pedagogically acceptable sequence (writing a book for students and
teachers) in which energy is introduced without relying on the concept
of force, or other concepts (such as work and pressure) that are now
defined in terms of force.
Yes, pressure can be viewed as energy per
unit volume. But that is not obvious, unless a traditional sequence is
followed up to the point at which the P*dV is shown to be the same
thing as familiar F*x. And I also see the rho*g*h in your definition of
"head," where g stands either acceleration or force per unit mass.
Yes, we did inherit a traditional path from g to F, then to F*x and
eventually to P*dV. The reversed path from P*dV to F*x (and then to F
and g) can probably be constructed. But that would not be easy.
