Go for it if you're having regrets about it so early into the game. I know that it might seem like a lot to lose, but... if you dislike your map now, chances are that you'll end up disliking it later on also -and you might have more to lose if you choose to restart in the future.
I don't know if you're against Time Travel or not. But if you're worried about your shop upgrades, you could always set your DS date to June 9th/whenever you got your game and just time travel a bit. I know that some people are against time travel, but considering that you've already unlocked all of those things on your own I don't see how it could be a problem.
Otherwise you could just go ahead and play the game without any TT, 2 weeks isn't much time so I'll bet that you'll be caught up in no time
