I think I'd relish the challenge as well as the possible benefits (although I can only do it as an experiment; I'd have to drop it within a few months.)

You won't succeed without commiting to it.

In general you should promise your parents to quit the shedule at the moment you become ill.
In addition you could reduce all driving, if you own a motorbike for the first time to reduce that risk factor.

Their is no reason from a traditional perspective on sleep to believe that you die when you try Uberman. Traditional knowledge would simply say, that you won't get your body to awake on that shedule.

I just ask your parents, when I ask mine I also excepted resistence but their was no real resistence (then I failed for various reasons).

Have you ever seen a top athlete who doesn't value a good sleep?

People who do non-stop sports like the Ultramarathon or sailing use low amounts of sleep.

Ask any qualified health practitioner about that and they would agree.

Those people who speek about would say that it isn't possible to live that way for more than six month (which Steve did). That makes them unqualifed on the topic.
In general I don't know for most athletes how much they sleep.

But I know that a large study has shown that people who sleep six hours per day have a higher life expectency than those who sleep eigth.

In general our postmodern culture is poised with the meme "More is better".
Get more money, get more sleep, get a larger house, eat more vitamins, get a bigger TV etc.
More isn't the answer to our problems.

I'd be careful with it because polyphasic sleep can upset your delicate stress hormone balance and cause health issues such as weight gain by throwing off cortisol levels.

Nobody of the people who tried it reported massive weight gains.
