[Zope] Converting LazyCat to LazyMap?

Hi All I am querying two catalogs seperately, each returns its results as a LazyMap object. I now want to combine the two result sets, but when I do that they become a LazyCat object (which doesn't work with the Plone Batch scripts I am using) Is there anyway to turn the LazyCat object into a LazyMap, or combine the two LazyMaps without creating a LazyCat? Any answers, suggestions, or stabs in the dark welcome Charlie
