Maybe I am not familiar with flexing MTOW's either, but I would imagine that it's not possible for Ryanair to have their cake, and eat it.
The only reason to certificate and declare a reduced MTOW is to reduce the Eurocontrol charges. I am sure one cannot be permitted to exceed the reduced certificated weight for ANY reason, irrespective of what the Type Certificate Holder (Boeing) states....unless one applies to recetificate upwards again.
