I guess u can call it great gospel, minus the angels, wait...tewcnically Aeris is an angel so yea...dont see why not that could be a limit break! Most of the limit breaks are subtly put in anyways :P

He also tried braver on sephy but missed!!

Tifa also did part of her limit Somersault i think its called...i dont know about this but i think u can count barret using a limit break, the first level one, except it was green in the movie...hmm!

And i think it IS Sephy someone mentioned it on another forum how sephiroths characteristics were split into the three SHM and when u have jenovas cells that started it all, you know put the two together and you got your mix of a badass villian!
