Literally all those characters need are better sculpts and materials that won't deteriorate. Hard plastic for the Aliens, genuine leather for the Terminators. Howard can open the floodgates on those licenses without the "artisan" bells and whistles. As long as they look like what I saw on film and don't flake apart in two years, I'll buy them. Simple as.
Howard is sitting on a pile of money he has no interest in exploiting for some reason. The generation that wants Indy/Alien/Terminator/Predator/Die Hard/Matrix/Mad Max/etc is still going strong seemingly. I'm not sure why he's waiting for us all to die off.
He's stuck on the same two franchises that are also mostly churning out junk for the sake of relevancy.
