Take, for example, East Ham ( signalling diagram available on the main site). Suppose a train is detained at signal A927 and it becomes clear that a major failure has taken place up the road at Barking. The train at A927 is, I believe, beyond the limit of shunt, assuming it isn't stopped unusually far from the signal, but it is not that far beyond it. Would it be possible at all to set back to wrong-road shunt signal FE4 and pull into East Ham platform, carry-over issues aside?

Technically it can happen and I don't think A927 is far from the limit of shunt anyways but I don't know if the rules would allow it, but like anything in a emergency rules go out the window in extreme circumstances.

Be careful with your wording!
Setting back in the context of London Underground rules means putting the train in reverse and driving backwards. This can only be done in particular circumstances and is not the appropriate procedure in the example set out in the OP.
A927 is far enough beyond the limit of shunt that the correct procedure in this instance would be a wrong direction move with the extent of the move being as far as shunt signal FE4.
