Abrams is notorious for putting incredibly blatant attempts at pandering to fans in his works, which frequently backfire because of how on the nose and predictable they end up being. If he really does include this, there's no way it would be anything so subtle that only a few people would notice. Abrams does not do subtlety. Anyway, it's still a dumb idea. I don't want to see or be reminded of Jar Jar at all. What the movie really needs to do is just focus on telling its own story and leave the past where it is.
Of course, seeing how they're handwaving away the supposedly-happy ending of RotJ and rehashing the Empire as antagonists, it may be too late to hope for something like that. inb4 Benedict Cumberbatch is cast as a clone of the Emperor. They should exclusively refer to him as Sheev.
