Agree with most of your analysis, however:
Boxers with good footwork give Tyson all types of problems. A Cus D'Amato Tyson who would wait patientely, go after the body first, then throw the cross/hook/overhand would have fared better against Ali. Ali could slip, bob, weave and take punishment. His footwork allowed him to cut angles, get in, strike, then tie up or get out of range and blister opponents. His will, jaw, and abiltiy to take punishment is legendary. I don't think this would be a close fight. Ali by sixth round TKO or KO.
Agreed, however Ali's weakness was power so the fights were rarely over as fast as you claim, it would've taken longer as it did with most of his fights.
As i've mentioned the closest comparisons would be Douglas-Tyson, since Douglas was for one fight a great boxer not dissimilar to Ali and thus a good proxy for Ali, and Foreman against Ali, as Foreman was an excellent proxy for Tyson. Douglas for that one fight just after his mother died finally finding motivation and realizing his potential as a great boxer not dissimal to Ali. He always had the physical part, and for that one fight he had motivation married with Ali's boxing skills, height and reach and see what happened.
Tyson never proved for the most part that he had the guts to stand in with a good fighter if the fight didnt end early, similar to Foreman. Foreman was just as awesome but also had the same weakness, a lack of endurance and guts to last 15 rounds when needed. Hollyfield's ear was bitten in order to end the fight he didn't want to be in, because as his ex-trainer said Tyson was essentially a coward when not able to be a bully. He was not mentally tough as he would've needed to be against great fighters.
Best examples of proven formulas to beat Ali were the first Frazier-Ali fight, before Frazier had been hit too much and before Ali used excessive holding that refs allowed him to get away with in subsequent fights without penalty, and Ken Norton, who in effect beat Ali 2 out of 3 fights despite the outcomes.
