I don't think so.

Consider for instance the following kit:

• Olympus E-M10, 396g, 11.9x8.2x4.6cm
  
• Ultra wide-angle: Olympus 9-18 f4-5.6, 155g, 5.7x5cm
  
• Short standard zoom: Olympus 14-42 EZ f3.5-5.6: 91g, 6.1x2.3cm
  
• Tele lens: Panasonic 45-150 f/4-5.6, 200g, 6.2x7.3cm
  
• Portrait lens: Olympus 45 f1.8, 116g, 5.6x4.6cm
  

With this kit, you're covered from 18mm (FF equivalent) up to 300mm, including a 90mm fast portrait lens.

Total weight: 958g

Carrying 2 extra batteries is pretty insignificant compared to how much one would have to carry by using another system.

 

I challenge anyone to come up with a similar kit for APS-C or FF that would come close to that weight 

 

Plus, the APS-C lens selection from Canon/Nikon is rather poor, with many holes in the line up (no 20, 24, 35 and 85mm FF equiv. lenses, no 70-200 equiv., no, long zooms, etc.).

 

The only APS-C manufacturer featuring a somewhat complete lens lineup is Fuji, but the size is not even close to MFT.

 

 

Coming back to the original message - if you take similar DoF capabilities as the baseline, the MFT advantage is nil.
