  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="b[a and not(a[2]) and not(node()[not(self::a)])]">
    <a>
      <b>
        <xsl:apply-templates select="a/node()"/>
      </b>
    </a>
  </xsl:template>

might suffice.
