NOT A TEACHER
The first sentence makes little sense because you can't go back in time. It only works IMO if you can actually go back in time, so I can imagine it being said in a movie or in a fiction book. The second sentence is fine in my opinion.
By the way, your first sentence is similar to, 'I'd like to play golf yesterday'. It just can't be done, unless you have a time machine.
Let's see if there are other opinions.
