Its possible, why not? Madara did susanoo with kuruma.
Kurama's body is about the same size, if not smaller than gamakichi. Naruto should be able to use his chakura koromo on him. Sasuke too.
But that will leave sakura's slime exposed and it would be wierd.
Will gamakichi with nine tail chakra cloak and sasuke's snake with susanoo happen?
*sorry I am really bad at english.
Dude, that sounds sexual... >_>Uu
