An interesting positional grouping problem.
My first thought is a two-pass approach. First wrap the offending elements
individually in a <merge> tag, then do a positional grouping to merge
adgacent <merge> elements into a single <p> element.
The first stage is easy:
<xsl:template match="content.body/text() | content.body/em | ...">
<merge><xsl:copy-of select="."/></merge>
</xsl:template>
The second pass is trickier (positional grouping always is); I naturally do
it with saxon:leading(), which selects all the nodes in a node-set that
satisfy some condition, stopping at the first one that doesn't:
<xsl:template match="merge[not(preceding-sibling::*[1][self::merge])]">
<p>
<xsl:copy-of select="saxon:leading(following-sibling::*,
saxon:expression('self::merge'))"/>
</p>
</xsl:template>
The alternative is a recursive template that continues processing successive
elements until it finds one that isn't a <merge> element.
This might be a good one to add to the grouping use cases for XSLT 2.0
