When I showed the project to my team the enthusiasm was high, so I think you should not be afraid of team response.
As far as ROI, it is a snap to integrate, and requires no code change in its basic form. (just adding a single annotation to your class)
And last, if you change your mind, you can run the unlombok, or let your IDE create these setters, getters, and ctors, (which I think no one will ask for once they see how clear your pojo becomes)
