One problem. We cannot penalize a child for dual citizenship of his parents, or even his own dual citizenship. Remember that another country can even involuntarily confer citizenship on anyone.
Suppose for example that Sarah palin was our republican nominee in 2012. Any country in the world could confer citizenship on her and make her ineligible to run.
Therefore only foreign citizenships that you applied for, or renew, as an adult should play a part in making a natural born citizen ineligible.
If Barack Obama could prove he was born in Hawaii and his birth father was an American too, I would give him a total pass on having been given Indonesian citizenship as a child. However, there is circumstantial evidence that he renewed his Indonesian passport and traveled under it as an adult.
