I also think that there is a possibility that kekkei tota are some manner of kinjutsu that are exclusive to a village/clan/etc. This isn't a completely new notion (Deidara taking the Hidden Rock kinjutsu, Kakuzu taking the Hidden Waterfall kinjutsu), and this might explain why it is exhibited in two unrelated individuals.
