I would rather use the Grant Peterson method of installing drop bars very high. You can ride in drops when you are feeling good and use the hoods or tops when you want to sit up.

If you can add some spacers and put on an “up-jutter” stem, you will have saved considerable weight, complexity, and “reversibility”. The installation on the speedlifter looks permanent, and as you already observed, does not appear to give the user a good way to adjust the headset.

This is also a good case for a long quill stem. Only one bolt needs to be loosened to raise the bars, and can give considerable adjustability. You would have to replace the fork and headset, but this should not be a problem with a normal head tube. If you have tapered or oversized head tube, then you are out of luck.
