The Dalai lama indeed has already lost credit and made contradictory statements before, especially regarding the topic of Dorje Shugden, so why not being contradictory once more, but this time to fix things up, make peace with China and therefore participate to the effort from China to bring civil peace in Tibet once and for all!
The very thought that His Holiness would give up his credibility and look like a fool, maybe a traitor by some extremists so that he could:
(A) definitely lift the ban,
(C) bring civil peace to his people in Tibet (and outside) for good (by undermining any further effort from any party fighting for an independance of Tibet),
(C) and then go to China (Tibet) to bless its people and the land before he leaves this world...
that very thought makes me rejoice, for it would be the last expression of the skillful enlightened actions of Chenrezig himself.
It would be a sacrifice of his reputation, it would be a huge clash... fo some time, but if properly done, it could be a stand for peace, it could be a stand for Dorje Shugden to come into the light.
Just as the last stand of the Dalai Lama, for we don't know if Chenrezig may or may not make his next rebirth relevant as a Dalai Lama...
But how? How could he do that?
This is only speculation of course, but he could negotiate with China for a pilgrimage back to Tibet (as discussed here above on this topic already), and therefore China would ask from him a number of things, amongst them perhaps:
(1) the removal of the ban,
(2) complete surrender of Tibetan affairs to the Chines governement,
(3) recognition of the Panchen Lama recognized by the Chinese authorities,
(4) why not even to remain in Tibet for the rest of his life?
The reality is that, FOR SURE, after His passing there is NOBODY, there is NO PARTY that can continue representing the Tibetan exhiled community when it comes to discuss Tibet with the Chinese authorities.There is NOONE!
My worry is very simple, in the future, if there is noone, but if we still have some extremist tibetans in exhile, the only way to "communicate" the cause (lost cause) of an independant Tibet would be terrorism, and that would hurt and damage the Tibetan culture, it would create ressentment towards ethnic Tibetan in China, it would also hurt Buddhism in the world because a lot of foreigners equate Tibetans and Buddhism and therefore watch their actions to form an opinion on Buddhism.
This would be ugly!
The Dalai Lama will not be there anymore, He would have to find a way to prevent this before he passes away.
Well... I don't know at all what will be done, I only speculate, but I am impatient to see what His Holiness next move will be, and I watch with faith.
