I think Obito and Madara knew that the Gedo Mazo could do this, but they didn't for two reasons:

1. It would take too much chakra from them, at least for Obito. I reckon Madara would have managed.

2. Both of them would rather not sacrifice their mobility. They'd just take the long route to defeating their opponents rather than insta-win with the consequence of being impaled and emaciated.

Nagato only used it because he didn't know all the abilities of the Rinnegan. Hanzo's troops would die by Chibaku Tensei, so Nagato probably thought that Phantom Dragon was the only option. Granted, it is OP af though, if Nagato used it against the 5 Kage, he'd most likely win, unless they pull a Hanzo and teleport away.
