I really don't think slb replaced sushant, rs only had two films released when slb offered him ramleela, so there was no reason to replace sushant with ranveer, coz ranveer wasn't a big star at that time. It is most likely due to sushant not being able to sign a slb film coz he had date issues or was committed to another film, so slb offered the movie to someone else, this is a common thing in bollywood where people are not able to do a film and so it is offered to someone else
And highly doubt sushant was offered bajirao and padmavat, maybe slb offered him films that he was going to produce rather than direct
Not talking about bajirao and padamavat but i have my doubts about ram leela or maybe as you said it can be one of the movie he produced.
