While axle width shouldn't matter if the I.S. specs for disc caliper are used with a disc compatible hub, hub specs for tandems can play havoc on what 'should' word. On the bright side, I believe the DT Swiss adapters come in a variety of different widths / thicknesses. Mark Johnson at Precision Tandems (or the folks at Santana) would know which one to use on a Santana with a Hadley hub and I believe Mark and/or Mel at Tandems East carry them in the different widths.
