Just tell the alignment guy your problem and he'll probably just change the toe-im. I don't know if they'll be in spec but that should improve straight line stability. The young alignment guy might not want to do it so find the oldest, most ornery-looking coot in the shop and ask him. The price you pay will be increased tire wear.
