It is possible abter all :)
Following is the simplified example that should give you an idea:

-------------------------------------------------------------------------=
-------

XSL:
<xsl:stylesheet version=3D"1.0"
 xmlns:xsl=3D"http://www.w3.org/1999/XSL/Transform"

<xsl:template match=3D"/root">
<root>
 <xsl:variable name=3D"trio">
  <xsl:call-template name=3D"doA">
   <xsl:with-param name=3D"this" select=3D"a[1]" />
   <xsl:with-param name=3D"bCount" select=3D"0" />
  </xsl:call-template>
 </xsl:variable>
 <xsl:for-each select=3D"msxsl:node-set($trio)//trio">
  <set>
   <xsl:copy-of select=3D"a"/>
  </set>
 </xsl:for-each>
</root>
</xsl:template>

<xsl:template name=3D"doA">
 <xsl:param name=3D"this" />
 <xsl:param name=3D"bCount" />
 <xsl:if test=3D"$this">
  <xsl:choose>
   <xsl:when test=3D"count($this/b) &lt; $bCount">
    <xsl:copy-of select=3D"$this" />
    <xsl:call-template name=3D"doA">
     <xsl:with-param name=3D"this" =
select=3D"$this/following-sibling::a[1]" />
     <xsl:with-param name=3D"bCount" select=3D"$bCount - count($this/b)" =


/>
    </xsl:call-template>
   </xsl:when>
   <xsl:otherwise>
    <trio>
     <xsl:call-template name=3D"doA">
      <xsl:with-param name=3D"this" select=3D"$this" />
      <xsl:with-param name=3D"bCount" select=3D"4" />
     </xsl:call-template>
    </trio>
   </xsl:otherwise>
  </xsl:choose>
 </xsl:if>
</xsl:template>
 =20
</xsl:stylesheet>

-------------------------------------------------------------------------=
-------
XML:
<root>
<a>
 <b>1</b>
 <b>2</b>
</a>
<a>
 <b>3</b>
 <b>4</b>

<a>
 <b>5</b>
 <b>6</b>
</a>
<a>
 <b>7</b>
</a>
<a>
 <b>8</b>
</a>
</root>

Output:
<root>
    <set>
        <a>
            <b>1</b>
            <b>2</b>

            <b>3</b>
