As much as I would want to see a third fight, the Pacquaio - Marquez trilogy should be dead and not even be mentioned. Both of them are already in separate weight divisions. Pacquiao moved on to higher weights and Marquez was left behind. Don't get me wrong, they are both excellent in their respective divisions.

Manny is not going to get any benefit from fighting Juan Manuel. He will have to drain himself to go down to Marquez level or they will have to have Marquez blow-up to Pacquiao's level. It would not be fair to any of them. (Oh wait, I don't think Marquez will mind because he will get another big paycheck.) Whether Manny wins the fight or not, he will still be criticized for it and rightly so.

If this post does not make sense, then I will just have to agree with the above post of KananKrus.
