I haven't been to LDS services since the change from the 3 hour block meetings.
Now, I am most definitely a high church guy, so it was harder for me to connect to the service. I did appreciate the reverence; I emphatically do not like pentecostal style meetings (the rock band, hand swaying someone else mentioned).
I'm not sure how this would work in your context, but it didn't seem like worship to me because the vast majority of the 3 hours was spent with people talking. Talks in sacrament meeting definitely felt like the focus of the meeting, then Sunday School was like a class (understandable because of what it is), but then priesthood meeting was also like a class. So it felt like classes and meetings instead of worship.
For me, the rituals focus my mind, spirit, and body on Christ, so that I am worshipping. In the traditional Latin mass, there are many moments when the priest sits and waits for the schola (Gregorian chant) to finish. The symbols all around me, such as statues, stained glass, stations of the cross, the altar, etc., allow me to stay focused and worship and/or pray. The music, in Latin, doesn't distract because of the language, honestly.
Again, I'm not sure how this would apply to your context, since LDS services are decidedly low church. But, could there be (approved) paintings on the walls? Could there be more contemplative music? Could the ritual of the sacrament be elaborated/extended or somehow made to feel like the center and focus of the meeting instead of something that is done early on and then all the talks occur? What if the talks were removed and a separate meeting held for the talks, so Sacrament Meeting didn't have announcements, business, etc., but just music, both congregation and choir, and sacrament?
Just some thoughts from the outside.
