Anyusername, I saw that part in the Abarbanel and it’s also not relevant to your point.
The Yerushalmi has a story told by an Arab about a child being born on the day of the Churban and then disappearing. The story says that he is moshiach.
The Abarbanel is saying that don’t ask a kasha how can the GEMORO says he is moshiach if he died as in Sanhedrin 98b there is also an opinion that moshiach is DONIEL who has died. So both gemoros allow it in line with their respective views. The Yerushalmi can accept that it was that child, and the Bavli can accept that it was Doniel.
None of the above, however, gives you the right to add a third person to the list.
Btw at least now I understand the mistake you are making, but look it up dispassionately and you will see that what I am writing is the correct pshat.
