How possible would it be for the team to make a mode where you can replay instances from the msq, job quests, etc?

Recently they redid Steps of Faith into an instance, and I was curious to see what it was like, but I didn\\'t care to do New Game + or make an alt, so I went to YT and watched a video. And, not going to lie, I\\'m a bit mad that I can\\'t just go and try it out myself without doing the above listed. Same with the Lahabrea instance. There\\'s also plenty of instances I\\'d love to play again (the Naadam in particular).
