I don't think it's possible. The Juno uses specific antialiasing filters which is part of it's sound. Same can be said for the BBD stages. Unless you simulate both these things, you just have a normal chorus...
If you want to simply have a basic chorus but with the same rate as the juno, then sure it's easy, just look up online, I remember there are articles and github repos that contain studies of the rate and depth for all these choruses.
