If the sport option was available on day 1 would I buy it? Maybe. I passed on the 0.2 second improvement in the Roadster for $20k.
If it was a 1 second improvement in 0-60 and a corresponding power improvement at higher speeds for a LOT less than $20k, I would consider it.
Do I think they should risk delaying the launch of the car to do it? No way.
Once they have the production line cranking, should they work on the sport version? Yes.
Once they have the production line cranking, should they work on the AWD version? Obviously yes. They need to figure that out for the Model X anyway.
