I would think that Greer denying DCF 60 days would be the straw that broke the camel's back. It would truly show him for what he is, a renegade! I can't ever recall in any of Florida's high profile child abuse/neglect cases any judge bucking DCF. I don't think they will miss this opportunity to redeem themselves.
Greer will be a fool to dismiss DCF's petition for intervention. But that's what he's proved to be all these years - a fool.
I just read the news (no oral food, no medical testing despite new technology, no reconsidering of error), and this is the last item. I was just thinking the same thing you are. When Greer says no to this (and I believe all indications are pointing to him ruling "no" - he's THAT far gone), he'll be toast. This is IT folks. Pray very hard. Watch very carefully.
I may be wrong, but I just have this feeling....
