For 200BTC, you could generate 444444 such transactions.
This is 444444 * 225 = ~100,000,000 sigOps!
Or 100000000 / 20000 = 5000 blocks = 35day backlog.
This is for a fee rate of 0.0006BTC per KB (six times the standard rate).

Or even better, a 7day backlog for a fee rate of 0.003BTC per KB (30 times the standard rate).

This would have been a much more interesting DoS attack 'stress test'.
