This is awesome...

On the best days I like to try and stretch out my tosides like this, feeling the extension right from my toes through my spine and up my neck.  It's a bit dangerous to be so extended, the spine isn't in a safe position to absorb impact in this position, but it just feels so good!  (Green runs only, when the groom is near perfect.)

I will admit that the surfing toeside/bottom turn turn by Alex Knost is a bit of an anomaly. The textbook surfing bottom turn is just the opposite as exemplified by Tom Curren, one of the all-time surfing greats. Curren's toeside is more like the Japanese snowsurfer carves. An antithesis of the groomer freecarving that you are promoting.

One more extra slushy toe-side carve...

I love those full extension toe-sides, but it does put my weight too far inside and sometimes it causes me to slide out.  I need to work on stacking my weight over the edge better (particularly on the toeside).

The Alpine community learned a lot from skiing, and as a soft booter I've learned a lot from them, but I think there's a lot to be learned from the surfers too.

Snowboardering basically started out that way in Asia.

I was really working on my toeside turns at the end of last season. I loved a heelside bank, but I absolutely HATED a toeside bank. I'd inevitably get my weight too far to the inside.  I'm still not riding at the level I was last year, but I have corrected this issue.  Two things that really helped:

1) Riding a longboard at the pump track this summer.  They're all banked turns, so you really need to figure it out or it just isn't fun. 

2) Counter-rotation at the transition. I don't do this all the time, but it really does help me stack my weight when I need to.  Instead of bringing the rear hand/shoulder back, you actually bring it more forward.  This allows me to drop my hip into the turn rather than my whole upper body.  Lars touched on this in "The art of the turn" video, and the k-carving class 7 delved into it as well.

Actually I need to give James a lot of credit here as well. The secrets of Snowboard Carving really paved the way for me, and he clearly does illustrate the open hips. When I rode with him he was even telling me to get my hips more forward, but I just wasn't doing it on the toeside (old habits die hard).
