I totally agree that 10 and 16 are cosmically significant numbers, and this theory should be tested out as more info comes to light. I do offer one possible spanner for this theory, though it's a small enough thing: Larasium. When the Lord Ruler first came to the Well of Ascension there were 10 beads of Larasium, not 16. One he took for himself, 8 were given to those who became the first allomancers, leaving one which Elend ate at the end of book 2. Possibly derails the theory, but still supports the numbers 10 and 16 being significant.
