Hi Violet,
There is of course something special about all the yogas that are there in astrology, but the high-sounding names that are given to them and the big effects that are promised for them are not for real, which we get to see all the time. That was the point I was trying to make when I said that what the theories say about the yogas should not be taken literally as that would only disappoint.
I did explain my point, giving the example of Bhadra MPY in Athreya’s chart that it will give him the positive qualities of Mercury in abundance, and it will give a lot of positive in respect to his 10th house as the yoga involves the 10th house. And that is true in his case as we know. He is not a great soul, who is being worshipped by the whole world, as the name of the yoga that he has, 'mahapurush yoga', suggests. So if we go by the literal meaning of the name of the yoga, we are in for a big disappointment.
Coming to Jupiter in lagna, or Jupiter in Leo or Aquarius in an angular house, I don’t think they will give the same kind of positive effects that we can expect from Jupiter in ascendant in own sign/exalted in an angular house. Even the basic theories of astrology will consent to that. So it surely proves that when a Hamsha Mahapurush Yoga is formed, it will give superior results than placement of Jupiter in a friendly sign in an angular house is expected to give.
Jupiter in ascendant taking away all the negatives in a chart is another exaggeration of theory, which we should not take literally. We should just believe that that position of Jupiter will support the chart to a good extent, and not expect it to wipe away all the negatives there.
Coming to the theory of functional status of a planet, the first thing I would like to say is, as taught by Vaughn Paul, I take the trinal lords for all ascendants in a chart to be functional benefics, and the other lords functional malefics. I follow that rule, and when I mentioned functional status of a planet, I said so keeping that theory in mind.
But then, if we see as per BPHS, Jupiter is a benefic for Aries and Cancer ascendants. It is a neutral for Saggitarius ascendant and not declared a malefic in case of Pisces ascendant. So for these ascendants, the MPY made by Jupiter will work much better than in case of the other ascendants.
Now, MPY is formed not just from ascendant but also from the Moon. So if a planet, which becomes a functional benefic from the ascendant and makes MPY from the Moon, some more ascendants will be added to the list, where Jupiter will give very good results.
Yes, it is true that MPY will not give extraordinary results in a lot of cases because of which thousands of people born with such yogas don’t become great or even successful in respect to normal middle-class standards.
Yes, the talents that I have mentioned for Athreya will be found even in case of people with good Mercury, but the difference will be of degree, and that will make all the difference. Strong Mercury can make one intelligent and good in studies, and it can make an Einstein as well—the difference in intelligence being one of degree—one having super intelligence, and the other having just plain good intelligence.
A person with exalted Mercury as badhakesh will be maybe an intelligent person with good knowledge but leading an ordinary life, and a person with exalted Mercury in an angular house will be maybe having an intelligence that will make him a scientist, the difference in degree of intelligence making a big difference in their lives, both being intelligent though as promised in their charts.
And by the way, I don’t believe in the conpcept of badhakesh because every time I think of it a couple of questions come to my mind: how can the 9th lord become a badhakesh, which happens in case of all fixed signs, and how a yogakarak for an ascendant can become a badhakesh as well as it happens in case of Taurus and Aquarius ascendants! Something to ponder on.

P.S. 'Mahapurusha' means a great man, and to be great and still not be known to the world, doesn't happen that often. So I am sure it is a yoga for fame, too, though I agree with you that Rahu gives fame, and Sun also, I feel.
