Hi just trying to find out if it is possible to use a sand anchor to aid in self launching and landing

I think that if I was to plant the anchor then attach the chicken loop ,then walk the kite to the edge of the window and launch on to wing tip,walk to anchor hook in to harness then disconnect form anchor and ride away,
Reverse for landing.

Will it work ?
What else do I need to do?
Has anyone done or tried this?

Thanks in advance
Bring on the comments/sugestions
