The International Football Association Board has proposed a raft of new measures and the competition will be one of the testing grounds.
Video technology is set to be used to assist referees with key decisions during next season's FA Cup, while teams in the quarter-finals of this season's competition are expected be allowed a fourth substitution during extra time.
The innovations are among a host of exploratory measures that were announced at the annual general meeting of the International Football Association Board (IFAB) at Wembley on Friday.
FIFA president Gianni Infantino attended the summit of football's global law-making body and Football Association chief executive Martin Glenn confirmed English football is keen to take a lead in its flagship cup competition.
