This may sound far-fetched BUT, i believe that naruto and sasuke with kakashi's......

[The Chosen Ones]

......knowledge of kamui will somehow figure out a way to possibly enter the kamui dimension,who knows maybe naruto or naruto and sasuke have to do something that could either teleport them somehow to that dimension or maybe somehow naruto or naruto and sasuke together or individually might due a jutsu or whatever that opens up a portal to that dimension,it shouldn't be impossible for naruto and sasuke considering they both have the sages powers the same sage who could do anything and possibly create anything.

 

[Tantalus Thief]

Maybe. We will find out.

 

[BLAZE]

who knows
i will wait for ch though

 

[Yuse]

to soon to tell in my opinon but nice theory it could happen

 

[ShiroShonen]

Or they could have Minato teleport them to Obito

 

[Ryu D Hyuuga]

good theory defiant options cant be counted out all the pieces are in place so who knows
