I looked at the photos on your previous posting
There are some lovely effects but they bring to mind the 'show' or makeover garden. Lovely now but what happens later?
What comes after is maintenance ie weeding. I don't think you're looking at a labour saving plan here.
My advise would be to try it. Nothing to lose, you'll see what works and what doesn't.
A few points. mat forming thyme lets the weeds through and goes brown if it's over-shadowed for long. Scarlet pimperenel has no mat forming ability, it's a plant of field edges and bare places, not part of a lawn effect.
