It might be possible to digitally remove the offending elements (either puppet or CGI) Angel has managed it on some mockups and I manage to do it on a few too (it's no easy task).
If that fails building models and set segments are possibly the only other way.
Clearing the slate is one thing but then you have to decide on what to replace the elements with, my preference is more dancers like Oola and possibly a few more courtiers.
