Hello Wendy R,
What a fascinating thread this is.
It is rare for me to agree with 'all' the post-ees...., and it is great to see people looking out for you!
What a great advert for The Blue Room!
Can I recommend you seek specific help from a chandelier company. Maybe one like mine..., ** laughs out loud **. Though there are a few reputable ones out there.
If you would like to make contact we will be more than happy to offer some free advice.
We have experience with hanging chandeliers within theatres..., and have looked after several in London's west end.
If you do go ahead..., you will need some sort of 'dampening system', a highly rated back-up safety system and ideally, (as mentioned above) someone else signing it off!
Wendy, (or anyone else reading this)...., always feel free to reach out.
Stay Safe,
Gary
