intruiging idea honestly, but it wouldn't even need to go to that extent. we've already seen how the white zetsu can spread his spores through that technique, and that alone can be very problematic. just imagine, the alliance thinking they defeated madara's army, feeling relief and their wounded states, when suddenly the spores technique becomes activated! most of the wounded fodder average ninja get their chakra completely drained.
