It seems that you could put a step wedge in the enlarger and expose as follows: -1 5 100% 0% 75% 25% 50% 50% 25% 75% 0% 100%
Where the percentage is the percentage of total exposure time. I'd probably pick 20 seconds or some other number that is easy to calculate and adjust the f-stop on the enlarger lens to give the proper exposure for the step wedge. Plotting up the resulting reflection densities ought to give you a pretty decent idea of the relative ES and speed of these combinations and allow you to interpolate for the 'in-between' combinations. Is this too simplistic?
