I actually tried this, because I assumed that it would be so much more useful and easy to wear with the added length. I purchased the 6 motif RG to try out the extra length first, before making any changes to the sweet 16 necklace. Surprisingly; I did not care for it! With the delicate motifs, it actually looks better double wrapped at chocker length. It is hard to explain, but it looks a little unwieldy at the 16+6 length, at least on me it keeps settling to one strand at a chocker length and the other strand lower, instead of both strands staying a bit lower, which is what I had been aiming for. The two strands also wrapped around/over each other a lot, getting the motifs jumbled up and tangled. I hate unclasping, but for me it was enough of a "no" that my sister now has the 6 motif because I will not be wearing it this way at all. The advantage of the 16 is the simple elegance and carefree nature, and it loses this when it becomes longer and tangled. I think you could add a short amount to the length and be ok, but probably not enough to eliminate the need to unclasp.
