Not really, there's no reason to do anything like that. You can just change the XML before starting it. Or you can use transient domains if you want domain XMLs to be generated dynamically. It would certainly be possible to add a new hook which would work as a filter when starting a new domain, but using existing methods may be easier. Both migrate and restore hooks were designed as filters because they are (in case of migration) or can be (in case of restore) called on a different host where, e.g., disk image files are mounted in a different path.
