I suppose self-compatibility would be important if you wanted to make such a 'duplicate family', but I have trouble envisioning a scenario in which many people would actually do so. Copying personalities (presumably via an upload/download process) requires that we have very advanced nanotechnology, which in turn requires huge improvements in our ability to create complex systems. As a result, it should be possible to do much better than simply duplicating yourself.
If uploading is possible at all, it should be feasible to re-engineer an uploaded mind just like any other piece of software. You could run multiple instances of your sensory-processing and motor-control software in parallel, allowing you to control more than one body at once. For better fault tolerance you could even turn yourself into a collective mind, with local processing in each body so that they can function if your data links go down. Spread yourself across a few hundred humanoid bodies and a similar number of useful robots and/or vehicles, and you become very hard to kill. How's that for an interesting post-human mode of existence!
