Shield Blocking Model Predicates

Is it possible to set more than one blocking model predicate?

I'm currently trying to apply a dynamic model for a shield through an override predicate "custom model data". However, since shields have two "states", one being the regular model and the other being the blocking model, I would also need to set a blocking model for the dynamic shield, but it seems that once a default blocking model for the shield is set, another blocking model cannot be assigned since it shows the glitched black and purple texture. 

I would really appreciate any insight, suggestion or idea on why this may not be working as intended, and how it could be approached or solved. THANKS FOR HELPING!
