Not quite: the Emissive Armour is very likely to get hit, because of its small size, and it is *not* protected by the Crystalline ability. So, only shots actually hitting the CA components will be "negated": shots on non-CA armour will work as usual.

Of course, it will work as you say so long as the Emissive Armour doesn't get destroyed. I think a few Shield Regenerators might also help with increasing the CA's protection: if the enemy has to get through 40 more points of shielding every turn, more damage has to be dealt to start breaking down the CA, even if more than 150 damage is dealt at once.
