So, just go back to current time and then start in real time from that point and don't TT anymore if you don't want to. It can be fun starting over because you get a new town map and a new set of default villagers, but redoing everything you've already done gets boring fast. Are you really looking forward to getting your approval rating to 100% again before you can do anything? It was new and exciting the first time--the second time, not so much. How many sharks can you give Blathers for the first time before it becomes a chore?
My advice: keep everything you have and just change the date back to today and the time back to now and take it from there. Beware, that if you're making a huge time leap you may lose a villager (though if your village is down to eight, you'll probably gain a villager), which shouldn't matter that much anyway since you were contemplating getting rid of all of them.
Your milage may vary, of course. Doing everything from scratch (unlocking all the stores, unlocking the QR reader at Able's, getting the petition signed for Shrunk again and then waiting five days for Club LOL to open, etc.) may be what you want to do.
