It's nearly always better to do one job in one stylesheet.

I suspect doing this globally will actually give you problems, but you
can try it if you want. It's a positional grouping problem, easily
solved in XSLT 2.0 with

<xsl:template match="*">
  <xsl:for-each-group select="child::node()" group-adjacent="name()">
    <xsl:copy>
      <xsl:apply-templates select="current-group()/child::node()"/>
    </xsl:copy>
  </xsl:for-each-group>
</xsl:template>

You haven't said what you want done with attributes, this solution drops
them.

Positional grouping in XSLT 1.0 is harder, the best approach here is
probably a recursive xsl:apply-templates along the sibling axis.
