Many of the fights are going to need significant mechanic changes to be workable for 25, and to be decently easy. It's not feasible to expect four hit-capped priests for Rasuvious, it's way too casual to demand all 25 people in full FrR for Saph, and it's ludicrous to expect 8 tanks for 4h unless you make them so wimpy that a holy pally/resto druid in bear form can tank them.
