Yahoo Pipes - Unable to merge feed descriptions?

Given two RSS feeds with exactly the same list of title values, I’ve been playing around with Yahoo Pipes to try to figure out how to merge their summary values together with no luck.
eg.
feed 1:
<title type=”html“>foo</title>
<summary type=”html“>
<img src=”http://www.blah.blah/some_image.jpg”></summary>
feed 2:
<title type=”html“>foo</title>
<summary type=”html“>
<p/>This is another value for title foo.</summary>
desired output:
<title type=”html“>foo</title>
<summary type=”html“>
<img src=”http://www.blah.blah/some_image.jpg”>
<p/>This is another value for title foo.</summary>
Has anyone figured out how to do this within Pipes? If not, I may write a trivial python script to do this.
