It looks like MediaWiki 1.17 and later support this already, by calling updateCacheExpiry() on the parser cache output object.

The RSS extension uses this in its rendering hook:

     if ( $wgRSSCacheCompare ) {
         $timeout = $wgRSSCacheCompare;
     } else {
         $timeout = $wgRSSCacheAge;
     }

     $parser->getOutput()->updateCacheExpiry( $timeout );

In theory at least this should propagate the shorter expiry time out to both the parser cache entry and the actual output page's HTTP headers, though I haven't tested to double-check myself yet.

Great, that appears to be what I was looking for... I'll go explore the code now :)

Thanks, Rob.
