I think I would prefer to delegate that to a added template with a 
different condition:

 B B B  <xsl:template match="*[not(*)]" mode="merge-children">
 B B B B B B B  <xsl:param name="prototype"/>
 B B B B B B B  <xsl:copy-of
 B B B B B B B B B B B B  select="if (node()) then node() else $prototype/node()"/>
 B B B  </xsl:template>

It can merge "content" but the main obstacle with your task to be seemed 
to be the lack of order of the possible child elements, if you group 
elements on node-name() as I have done then you don't need them ordered, 
for xsl:merge to work you would need to have them ordered or would need 
to first order them, see
