They might need a bit of support but if you're that far into flushing then I don't think they're going to get much bigger, so might be safe.
Personally I would start trimming up some of those fans, save ya some time later and will also ensure good airflow around the flowers (helps decrease the chance of mold).
Ballsy growing out back like that! Be careful of rippers!
