It worked so well for Doctor Who...

I shall present you the likely case scenario.
Billie Piper flies the Tardis back to earth looking for the Doctor. The truth is yes, of course she's actually Rose. Rose now teams up with 14th Doctor so Russel can have his cake and eat it too. The goal is to spend a few seasons figuring out where the real 16th.
Russell may or may not actually complete his desired Susan/The Boss arc with Tennant instead. We all know Tenny's not against coming back to help bail out the show.
16 then gets to be a fresh actor for what ever showrunner has to salvage this mess.
