Arghhh!
I just spent the last 15 minutes in futility! I definitely remember a post that someone did a while back where the OP wanted to shorten the throw on the AT. I don't know if that would help you, but I recall he had use one soft rubber foot thingie (the kind usually used to keep a small appliance slightly off the counter) towards the base of each paddle shifter. This made the throw a little shorter and softer FWIW.
Perhaps another members powers of search will prevail?
I did find this thread to be somewhat interesting though:
