Interesting question. You can invoke the DOMConfigurator multiple times as much as you can invoke the PropertyConfigurator multiple times. (You can).
However, both configurators when they see a category definition in a config file will remove all the appenders in *that* specific category. Thus, in general, merging two property files and invoking PropertyConfigrator (once) is different from invoking PropertyConfigrator twice on the unmerged property files. Having said that, it is very important to remember that a category is defined in a single line (i.e. in a single property). Thus, if the separate properties are equivalent to the merged properties, then the two sets of properties are disjoint (they have no elements in common). The same principle applies to the DOMConfigurator. Thus, the short answer is just try and it should work.
