This is the one problem I've considered with this approach.  But, like you
say, no matter what you do with these graphics, you're going to end up with
something ugly.  If I were to encounter an inline graphic in our
documentation that was taller than the line-height, I'd either shrink the
graphic or break it out into a separate block.

This probably won't catch everything.  It will probably come very close,
though, depending on where you tend to place footnotes in your
documentation.  In most documentation, I would guess that about 90% of
super- and sub-scripts (either using those tags or the <footnote/> tag) are
contained within <para/> elements.
