The Divine Office is a prayer without equal but it is hard. You would need a fair bit of preparation and even rehearsal to avoid people getting confused. Even nuns practice before special ceremonies and they do it every day.
In my experience as a nun the Divine Office isn’t really something that gets “led.” There are maybe half a dozen versicles for the hebdomadry and that’s it. The reader does her part, the first chantress does hers etc. All the president does is read the Gospel on Sundays, not the other readings, and pray for the blessing at the end of Compline. It isn’t meant to be a one man show. I know priests say it on their own but it was built for communities in monasteries.
The Office is something that requires participation of all involved. You would need some very detailed sheets to read from because no way will laypeople be able to flip back and forth through a Breviary to all the right pages first time out of the box. Even for a brand new nun following along seven times a day in a community who knows what they’re doing it is confusing for weeks. The back and forth chanting of the psalms is something most people don’t see often, psalm 150 is sung together, not back and forth, and the structure of the Office is quite complex. It also takes a comparatively long time and a lot of people get restless. And even nuns who pray the Office seven times a day make mistakes. If we made a mistake we used to stand up, kneel for a moment, then stand again and return to our place. We were only allowed to do this three times per Office, to prevent disruption. Nuns sit together in their stalls and there is no distinction between them. They have assigned seating that changes each week. The only time they go into the sanctuary is to read from the lectern. Nuns are also forbidden to look around in the chapel, called “modesty of eyes” and have a special garment they wear over their habits when in chapel.
I’m sorry to sound so negative. I don’t mean to say it is impossible. Make very detailed running sheets for each person. Have a rehearsal. Show them a video, in the language you’re going to use, of the Office you’re planning. Make them feel like they are the ones praying the Office rather than sitting there while you do. Pick someone to be Reader, Hebdomadary, Chantress(to intone the psalms), candle bearers, someone whose job it is to go into the chapel beforehand and make everything ready, someone to ring the bell when its time to assemble- nuns have a bell to gather in the Chapter Room at, say, 0700, then eight minutes later a bell is rung for everyone to proceed to the chapel. Have a musicial play a processional while everyone is waiting.
Good luck and let us know how it goes.
