The thing about Susanoo/chakra avatar is that they arent hollow once the develop the skin layer. The user can pick and choose what comes in or out and the only way in would be to break it. For all intents and purposes they are solid once in the humanoid stage. If Tobirama cna FTG all the "empty space" inside is a bunch of chakra that Sasuke is in control of.

FTG into Susanoo/Chakra avater would either be like teleporting into a giant cement brick(its unclear if FTG would even allow one to teleport into space that is taken up by solid matter already) or telporting into a pool of jello.

The only for sure win would be to teleport into it during the skeletal phase or underneath it before the humanoid manifests its whole body.
