I have tried to adjust the _height_ of the mode-line face.  This caused
the last line of the text area to be displayed only partially and the
height of the extra space below the echo area did not change as we had
hoped.

I also tried using the display property:

,----
| (setq mode-line-format
|       (list "" 'mode-line-buffer-identification
| 	      (propertize " " 'display '((space :height (30))))))
`----

Also tried the above combined with t as the value of the line-height
property of the final newline.  (Which didn't have an effect at all, the
newline was displayed as ^J and the height of the mode-line did not
change; is there actually a way to have a multi-line mode-line?)
