"So there’s no way to use any of the Genesis 2 through 8 outfits at all?"
Genesis1-2 works almost ok. You can pose them without bugs. The worst part starts when you want to dress Genesis1-2 with custom body shape in clothes. There will be alot of bugs. To avoid them, you have to conform needed clothes to needed character in daz studio, then delete the character, and save clothes in .cr2, and do it for every needed character, so you'll have something like: shorts1_character1.cr2;shorts1_character2.cr2 etc.
"I want to get back in to use it"
i think you should wait until Poser12. Hope it will be cracked, my PC costs twice less than Poser 🙁
