No, this wouldn't work in the slightest. The "hypothetical" account would soon have the pains and limitations of an institutional investor... it would move markets so much that this wouldn't be possible to make trades as described. Perhaps a quant can run this on a market simulator using historical data and show how much it would diverge from reality.
