Just to clarify, I think that different component ratio combinations that achieve similar overall ratios will, and do, feel differently. On the other subject, something to remember here, since inertia relates to acceleration and since the key lever and the shank lever accelerate at different rates (i.e. the shank moves 5-6 times faster than the key), changes in mass on one or the other are likely to create a different curves when plotting inertia against acceleration for each component. That might suggest that comparable inertia with mixed setups cannot be achieved. The sum of the parts may not tell enough of the story. Maybe someone more formally schooled in engineering or physics can chime in here.
