There are a multitude of other names to choose from each of them would convey some sense of what your town stands for. The original people that posted were trying to be helpful it would be wise to listen to good hearted advice.
Besides in creating a town let it create it's own legend and sense of fear based on what you and your town mates do, it's lame to attempt to boost yourself up by adopting the moniker of others... especially when there are many of those "others" in the same world as you.
It may seem petty but to many the tag MC means something. To those who are a part of it; it stands for an alliance forged in blood, energy, cooperation, and loyalty. To see somebody else claim to be a part of that family will just rub people the wrong way...
However, in life there are always choices, I am just another voice that is encouraging you to make a smart one.
Happy hunting,
