Sorry but that has everything WRONG with it, it's a "cut away" rather than a scaled action. The action diameter and large barrel shank mean the stock has to be full size through the area where your hand goes when you carry it and the barrel shank is the same great hunk of steel that every normal action has.
I have two of the old time versions of super lights, a 2.6 kg Mauser Kurz "original sporting rifle" from 1921 in 6.5x47 (it was rebuilt), and a 1970s version, a Weatherby Varmintmaster at 2.7 kgs in 22-250. Both have what I think is an essential element for a super light rifle - a scaled down reciever with a reduced barrel tennon size - both of these are built very slim rather than being a full size action with bits hacked off here and there.
