I've tried to play this chord a couple different ways and I have no way to play it. I tried to have my index on 10 my pinky on the 16s and my middle or ring on 14. Is there something I'm missing or are my hands just too small?
I gave it a try with a fingering as you described. Not really convincing, but possible. The rest is a matter of practice.
If you are going for dextrous fingerings I suggest taking an electric guitar and starting as high up the neck as possible. You could probably hit something like
14-20-20-18---- right now. And from there you go down the neck and work your fingers wider.
