The basic idea behind C-x o is that it cycles through all live windows
before returning to the initially selected one.  We could, in your
special case, have ‘other-window’ select ‘other-window-for-scrolling’.
But if we do so, we have to face the dilemma that the next C-x o gets us
immediately back to the minibuffer window.  This means that all other
windows would get excluded from repeated invocations of C-x o.

So I'm afraid that I cannot offer a practicable solution for this :-(
