I highly doubt they would.
You joined early enough to have come on and noticed the name change thread, but you didn't, so it's your loss. And if you joined more recently (like today, for example), then I still don't think they'll let you go through it.
If there's a simple change, though (like a capitalized letter in your username or something), they MIGHT change that. But then again, they might not.
Even if you do disgust it, go with what Drew said and make a second account. Maybe even ask a staff member to delete this account of yours, since the higher-ups can do it, I believe.
