Is the approach not anyway that the racial starting values represent the lowest of the lowest possible values for a race, meanwhile a 6 represents the highest possible value even the force can grant.
Anyone want to argue that a wookie has more strength than Master Windu who demolishes droids with his bare hands? Still a strength 3 wookie is basically a weakling.

Now the scale is indeed a little small. Having 7 the absolute top maximum with cybernetics leaves indeed little room, but that is courtesy to the dice, characteristics and skill mechanics. If you fiddle here with the values, you are messing with the basic probability curves of the game.
@Absol197 The strongest Chadra-fan would be a force user in that case.
