Which boxers, trainers, and announcers should be cloned?

Some boxers are too good to let them just retire. A simple solution to avoid these retirements would be to clone some of the best boxers. The same solution can also be applied to trainers, announcers, and some boxing fans. Imagine a fight between Manny Pacquiao 2 and Manny Pacquiao 3 or a fight between Vitaliy Klitschko 2 and Mike Tyson 2. Imagine different replicas of Mike Tyson trained by Stewart 2 and D' Amato 2 squaring it off in the ring. Or imagine Floyd 3 ducking a fight with Floyd 2, and both of them ducking a fight with Mosley 2. Finally, some notable boxing fans such as Anorak can also be cloned to ensure perpetuity of nice jokes on this forum.
