The following transform, based on the Modified Identity
Transform pattern,
should do that (not tested though):

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

    <xsl:template
match="b[count(a) eq 1][empty(node() except a)]">
       <a>
          <b>
<xsl:apply-templates select="a/node()"/>
          </b>
       </a>
</xsl:template>

  This is simple: the first rule catches every node and
copies it,
then continues navigating through its descendents.  But the second
rule applies when the transform go through a special node: a "b"
element with
exactly one child (an "a" element).  In that specific
case it creates two
elements (a "b" within an "a") and continues
navigating through "a"'s
descendents.
