Honestly, having done about a ~1 hour commute to my foundation year back when I first went to uni, I am 100% certain this is not going to be sustainable. Even a 1 hour commute was absolutely exhausting to do every day, twice a day. Yours will be double that. Imagine you've been at the uni all day long, and your tired and maybe had a bad day, and then instead of being able to just go home within 10-20 minutes, you have to spend 2 hours on public transportation. Also if anything gets delayed or cancelled on a commute that long, you basically miss a whole day of uni.
Then there is the situation if you have just one or two lectures on a particular day - are you going to want to spend 4 hours travelling to go to just those few lectures? Also consider what if you have a 9am lecture; you would need to be getting up probably around 6am to get ready to start your commute (assuming that there is even a bus that goes early enough for you to get there in time).
This is just a spectacularly bad idea.
