I don't think a Spencer vs. Manny will ever happen. Neither will Crawford vs. Manny. I doubt the camp of Manny will allow such very risky matches. They are now protecting the old man from facing very talented younger fighters such as the two fighters I mentioned.
Manny Pacquiao is still a great fighter but I love Manny Pacquiao that I don't want to get him hurt, these two boxers Spence and Crawford can hurt him because they are to dominant, they are at the peak of their skills and power, let these two boxers have it and fight each other and just leave Manny, I like Manny's like fight to someone body like him like Mayweather if he still likes it. or Mickey Garcia.
