Looks like only Garcia is pushing this fight to happen, then there's no official discussion base on the article I shared has been discussed by Mayweather's camp about this plan of Garcia's camp
Most likely this fight will not going to happen again, since I think Mayweather is pretty much serious to defend his no losses record. But if they will sign an agreement that this is an exhibition match. Maybe Mayweather might agree on this planned bout.
I no longer believe any rumor about Mayweather fighting at this point, not until I actually see him in the ring during fight night.

First of all, he's already too old. Secondly, I doubt he's willing to risk his 50-0 record. He didn't even want a real rematch against Pacquiao, only an exhibition match.
Fair point. Since to many rumored fight has passed, but there's none of it happen in reality. I think he's serious on defending his no loss record. Then will just agree once the offered fight is just an exhibition match.
Imagine how big the profit he could get if he just agree on those fights. But well I think his ego won't let that to happen, that's why he got so many cancelled fights.
But well maybe if Mayweather got reported to be completely broke, he might agree to deal with those people just for the sake of getting millions of dollars again.
