I read the same article and have decided to revert to bat on the floor behind my feet as I used to bat when younger. Looking back at all my big scores they were all made batting like this. 50 yrs old .. who says you can't teach an old dog some old tricks 
I'm also getting on a bit, and remember what an 'orthodox style' used to mean. Side on, bat down, feet closer together. Think Boycott and Bradman; OK, I'm not that old.
I read the article too, and watched this compilation of Mark Waugh [
https://www.youtube.com/watch?v=DuwKVnLDfPk ] for inspiration. I thought I'd give it a go, but this is what I discovered. My more open stance allows me to face forwards more comfortably, with less strain on my neck. Also, I now grip low with my bottom hand (ooh matron) so that tapping the ground requires me to bend my knees so much that I feel I'm crouching. I understand how the tapping can aid rhythm and timing (you can see it in the Waugh video) so I'm trying for a mid-air tap; if you see what I mean.
But as Buzz suggests, there is a danger of thinking about it too much.
