If the structure of your input XML is fixed, we can achieve the
desired output by hardcoding the structure. I can suggest something
like below:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:output method="xml" indent="yes" />

  <xsl:template match="/X">
    <X>
      <Y>
        <Z>
          <xsl:copy-of select="Y/Z/*" />
        </Z>
        <xsl:for-each select="Y">
           <xsl:copy-of select="*[not(*)]" />
        </xsl:for-each>
      </Y>
    </X>
  </xsl:template>

</xsl:stylesheet>

But if you want the stylesheet to be generic, which could handle any
input XML, and merge the nodes, I think it will be slightly difficult
to write such a stylesheet.
