I did a three week PPL course about 30 years ago. At the time I had been flying gliders for about 5 years before that, so the flying part was pretty easy. I also passed the written before starting the actual flying. Even so, it was pretty intensive. We lost a couple of days due to weather which didn't help. Then, having consumed my entire flying budget for the year, it was about a year before I flew again. I would imagine that trying to do it in two weeks would be absolutely brutal - particularly as there is more to learn these days.
Having said all that, I have read many *many* reports from people who went the conventional route and of course, many of them gave up. So I don't regret taking the three-week route.
I don't know if any of that helps you, but good luck either way :-)
