Well, now that we know its your wife in the sig. - My advice is keep her happy!
One clutch would be a small price to pay.
On a serious note. It can be done. I taught my wife to drive a stick many years ago. And to be honest she is smoother on take off than me!
Just find a huge empty parking lot and be patient. The LS3 is such a torque beast that if she gets past the stall point on a slow roll that big ole motor will do the rest of the work.
Good luck and go for it. It could work out to your advantage as you never know when you will need a DD after that next party.
