What exactly is it that you want in a sport/performance option?
And frankly, if the test drive come February WOWs me, then I agree, the sport package may not be that important.
You need a faster 0-60 than 5.6 seconds?
I have never seen a sport option defined.

0-60 in 4.4s was considered a target.

MODEL S - Sport 0-60 in 4.4s? AWD options? | Forums | Tesla Motors
I don't think that developing another drivetrain and the system to control 2 of them would necessarily qualify as the easiest. That sounds complex to me.
In the Roadster acceleration is PEM/motor limited until about 50mph, above that it is battery power limited.
If the Model S is similar, then there isnt a lot of extra battery power for the 2nd drivetrain except below 50mph, so just adding another one may not improve performance at all above 50mph.
