A custom toe link with more adjustment would do the trick I assume. I would love to say contact MikeR

I know some people have made their own, and TVT had some way back when they existed. You would have to do some searching but I assume you could find a set or someone to make them (not sure if speedy Benz has them) If I remember they are basically the same setup as the camber arms just shorter/smaller. I'm guessing a couple hundred max for the set which compared to rear tire prices is not much.
