I second this! Good thinking, Gareth!

As I wrote earlier, a slightly different but related idea,

And the existence of a superhaplogroup that includes I and J has, I
think, been proposed. I think I read this a long time ago in some
earlier papers -- don't know whether the idea was dropped as unlikely,
or what.
