Yeah I've been thinking about this one as well, because as it is now the lofted back foot cover drive still looks really awkward, and no one really plays a cricket shot like that.
I was thinking as a substitute you could have a baseball style horizontal bat slog over the covers, even though that would be played on the front foot it would make more sense than the animation that is in there at the moment.
@funnyadit's suggestion is good also to keep the animation the same as the regular back foot cover drive but make the ball loft off the bat.
