You've brilliantly solved your own problem, so this may be a bit late, but…
using the commands and mappings described in :h preview-window might get
you close to your workflow. Off the top of my head, assuming you start from
a single window:

:ptag or <c-w>} or <c-w>g} (to open a tag in the preview window)
<c-w><c-x> (to exchange windows)
:se nopreviewwindow (to turn the preview window into a normal window)
<c-w><c-o> (to close the other window)

and repeat.
