How bad of an idea is this?

[BLINGMW]

I wanted to run my Azenis for one more track event. Just a single day at little talledega. They're down to ghost tread, which would be great, but the inside edge of a right front (since I have a bit of camber and was driving around on the street too much) is starting to show a little cord. With that tire on the inside rear, with not as much camber, do you think they would survive another track day? Or is that the dumbest idea you've ever heard? How much rubber is left when cords are starting to show? I don't know! :?:

(there probably won't be any sort of tech inspection, this is a bunch of Xtreme measures instructors, and plenty of people will be showing up with shot tires)
