  The torque in both versions would be the same.
  
  Your first version just adds 3 of these gears:
  
  [![gear 3648](https://i.sstatic.net/3v8fBs.png)](https://i.sstatic.net/3v8fBs.png)
  
  The ratio between them is 1:1 so it will be the same as if you connect the axle straight into those small gears, as you do in the second image.
  
  (Well, technically speaking, having 3 more gears in the mix will sacrifice some power to friction, but the theory is the same.)

  If you are, then it simply will not work.
