Hey @Zeondinus,
Thanks for jumping in here, I think the initial question here was whether or not an account could be transferred from one operating system to another.
Just like on STAR WARS™: Galaxy of Heroes, The Simpsons tapped out is tied to either your iOs or Android system account and your progress isn't transferable from one account to another.
EDIT (21/12/16) : I apologize for any confusion I've created here and I'd like to thank @DracoDITS for bringing this mishap to my attention. The Simpsons: Tapped Out does indeed function differently than Star Wars Galaxy of heros as The Simspons: Tapped Out is linked to the Origin Account whereas SWGOH is linked to the your iOs or Android system account.
The progress for The Simspons: Tapped Out is shared across platforms due the progress being shared across your origin account which is not the case for SWGOH, implementing this on a live game seems very unlikely.
Thanks,
Roger.
