Yeah i think they are. I wish Neca, SH Figuarts or Mafex did movie Ghostbusters. We have never seen accurate likenesses and equipment in pretty much no GB figures except the Blitzway ones (which, btw, they were going to do 1/12 GBs, they showed them off years ago and never actually produced them).
Neca would do a great job with the suits and proton packs, and include everything they need, but maybe wouldn't pull off the likenesses (or maybe they would?). And of course they would be pretty stiff in articulation. SHF would certainly do some great poseable figures, probably with very accurate suits and proton packs, and maybe some great likenesses, or not. Just not a lot of paint. Mafex would go all out, I think, and make the best possible 1/12 GBs figures, at their ultra high price of course.
I really thought SHF would announce some back when the new movies came out, like they did with their Indiana Jones, but it never happened. So at this point, who knows? Maybe Inart or LPZZ grabs the license and knocks it out of the park with it. But they seem too concentrated on DC right now so I wouldn't count on it.
