I like the test and ultimately I agree with the point you made in the opinion section that some EQ could bridge the gap even with the different pickups. 
For the SSB I built, I went to a 49-109 gauge set of strings to offset the loss of tension which I think contributes to the longer scale bass sound. It sounds great to my ears, but more importantly it has inspired my dad to play more often because the bass is so light and the stretches are less intense.
