Honestly a good question, and I'm a bit rusty on the regulations, however for several years was an instructor and we did many accelerated ATP ratings. Normally if the applicant was proficient and met all the time requirements this was basically a 2-3 day course, getting them sharp for the check ride . I did look at the regulation and there is a change after July 2014 that I don't understand.
My best advice is to contact several schools that offer ATP training and see how they handle this.
