Yes, shield battery work, just look at the shadows in my screenshot with blue fires...

You could try making the warmth effect - like you see on hot roads - the air sort of flows - creates mirages in the desert - off topic tho - the effect could be made with observers, would be kinda cool.
Of course, too easy, let me explain :
-use p14 scanner sweeper just like in topic
-put carriers (in movment or not, see what better) at the place you wanna the effect
-put (an) arbiter(s), so all carriers are cloaked
-when p14 scanner sweeper is ended, remove the arbiter(s)
-now you got effect, and obs will not see carriers
