That analysis of my theory is flawed. It assumes the Doctor's own personal assumptions about the situation in which he found himself were true, and he's been wrong on many times before, only realizing the truth once a key clue becomes clear.
While he says the time web is his personal time stream, he's just acting on an assumption. When he uses the sonic to listen in on the stream, the voices of previous Doctors can be heard (reinforcing his confidence in the theory), even though such voices would still audible from the TARDIS own time-stream since she's been everywhere he has.
While he can only (again) assume he's buried there, based on how the weight of the evidence appears at first glance, that's no proof that he's incorrect and has somehow found a way to fool himself from the future knowing he wound up there in his past, not wanting to give hints away.
He didn't even realise River Song's grave was a back-door to his tomb until River herself pointed it out. Who put that back-door there, and why? I think the Doctor himself left that secret entrance behind, when he abandoned the dead TARDIS and left Trenzelore, knowing his earlier incarnation would need it.
His line about bodies being boring proves nothing. It can be assumed that Rassilon's body resided within the Tomb of Rassilon, and other Time Lords have been able to find ways to manifest themselves despite being dead. There was no sign of this. The Doctor's line didn't mean he won't have left a body behind, just that he wasn't interested in it.
But if it wasn't in the control room, where was it?
