I think the move for this ride would basically be to go straight at the top of the lift hill, have a run off and another lift hill to reconnect to the existing track. Otherwise, I don't see a logical way to do it.
I think a better move would be to remove the attraction entirely, but only after they re-develop Chester and Hester's. The ride opened in 1999 and you could conceivably get 30 years out of it before they're ready to expand / re-develop that area.
I'm waiting for the day an underwhelming attraction like Kali gets turned into a pre-show of sorts. Not entirely unlike the shuttle at the first section of RotR. Or a simpler example, the train to planet watch.
There are several attractions on property that could be reconfigured in such a manner and give it new life. IMO.
