The latest BRB FAQ was largely a by product of the psychic prevalent GK Codex, but given the update, is it now possible to stack Fear of the Darkness?

You obviously need to run two Libbies with one squad so that FotD fires off simultaneously and effects the one target at the same time. So would this equal an immediate -4 Morale check? I have an opinion myself based on the wording of the FAQ, the FotD text and the rulebook 9largely that it is possible to do so), but keen to understand what others may feel if it's different.

Thoughts?
