This is an idea from a chemometrics professor, Riccardo Leardi, at University of Genoa. (Not a JMP user)
The "normalized determinant", M, is used as a measure of how good a design is.

The optimal design for different run sizes are determined. M is then plotted versus number of runs to suggest the appropriate number of runs to use.

This (or a similar metric) could be a useful plot for Compare Designs and/or Design Explorer.
There is more detail in this paper:

This approach can be utilized in CAT (Chemometric Agile Tool) software, which I think is based on R. I have never come across anyone using this software, other than Prof. Leardi.
