What 'top' pros are going to be interested though? As mentioned first they are going to have to qualify and then prepare for fights they do not get paid for... Sure, if you are a youngster who wants to make a name for themselves it might be attractive, but it seems it would be a bit of a slog for an established pro to write off a year of their career to do it.

With qualification already active for Rio I think it is non starter this time around, so it will be interesting to see who in 2019 is going to go through what will be needed to fight in the 2020 Olympics; I suspect it will not be many 'names'.
