Although, yes, reimagined Borg could be awesome. Using CG to replace or remove body parts (a lower jaw, part of an arm, part of the torso etc), and replace some with machinery would make them look far more scary than just wearing rubber over the top.
Sure but the best Borg stories (Q Who, Best of Both Worlds and I, Borg) worked well although they did not look particularly scary and FC worked not because but in spite of their zombie looks.
I am not a fan of the shift from the Borg as more of an ideological enemy to this Cronenbergian "assimilation is so horrible" stuff.
"BOBW" and "family" portrayed assimilation as pretty horrible. That wasn't exactly a FC revelation.
