Update your Gnus (and make sure, your emacs has PNG support) and take a
look at the gnus-treat-display-face (defcustom ...) (as opposed to
gnus-treat-display-xface; both in gnus-art.el).

I think, the documentation for it isn't accurate, but I believe, that
it's the nearly same thing as X-Face, but using PNG compression. (Please
correct me, if I'm wrong, anybody.)

Turn on picons, so that you suddenly have little pictures exploding
all over your screen, and suddenly you won't care where face pictures
go. :-)

Yes, but you need Oort.

Using the space-width it becomes a little easier (insert one space
with the space-width property and then the face, then increase the
space-width length until it can't be increased further without
wrapping the line), but I think it is impossible to get the above
because an image cannot occupy several lines as far as I know.

So it is only possible to get the following:

 +-------------------------------------------------------+
 | <header...................>                   <X-face>|
 |                                               <X-face>|
 |                                               <X-face>|
 | <header...................>                           |
 | <header...................>                           |
 | ------------------------------------------------------|
 |  <body..........................................>     |
 +-------------------------------------------------------+

Another idea is to make use of multiple emacs buffers for this, i.e.:

 +---------------------------------------------+--------+
 | <header...................>                 |<X-face>|
 | <header...................>                 |<X-face>|
 | <header...................>                 |<X-face>|
 | <header...................>                 |        |
 +---------------------------------------------+--------+
 |  <body.........................................>     |
 +------------------------------------------------------+

If the status bar and scrollbars can be disabled or minimized (which I
believe is the case), I think this could work rather well.

Presumably, the easiest way to implement it would be to simply disable
viewing headers in the current *Article* buffer and then add the two
other buffers with the headers and X-face, like the tree buffer is
added now.  I'm not sure if it is worth the trouble.
