I completely believe the vast majority of the faithful who travel to Amaroo would delight in it if he revived all his old costumes and customs. 

I think he might actually get more new followers not less if he went full heavy devotional era #3 with darshan, the mala, the crowns, Holi and the spectacle. 

I could be wrong, but reading the comments on his YouTubes or books, I don't think I am.  He might not fly under the radar so well because it's so cinematic, the old extravanzas. He likely wouldn't get the same numbers in the West, but I think if he revived the show he might get more coming to see it. 

Yes, I believe some are just waiting for him to do just that and when he does they will congratulate themselves for never losing faith in who He is and always has been.
