I don't think so because 1- i'm pretty sure they needed all 12 keys to open it 2- They couldn't have opened the gate because they needed a massive amount of magic energy to open it. Hence the grand magic games. Which they never had before. 3- Even if they some how opened the gate why would they use it to get two little boys and not dragons and igneel and the other dragons wouldn't have known what the gate did so why would they have sent their children into it. 4- wouldn't Lucy know how her mom died? 5- didnt they start building the gate during the 7 year time skip?
