I have not much experience with extension tubes, but I think it would give a different result. It wouldn't be that wide and combined with the 20mm lens you couldn't get the same macro capability. Actually I've recently tested the 16mm pancake lens with +2dp and +4 dp and I couldn't reach similar close focus results and the perspective was also completely different.

...with the +4 diopter MFD will drop to about 25cm.

And as in both cases the DOF will be also quite shallow (even with WA 16mm lens) as diopters tend to do this to DOF, the setup might be fit for larger subjects.

Or... for targets which tend to move rapidly, and thus one will need a lot of spare space around them,

I've finished a test with many lenses and lens combination I found at home and posted the results on my blog. It worth a look at it to see the differences in the perspective, background, bokeh, sharpnes DOf etc. between these set-ups.
