And while SDO is just about OK for dealing with the last one or two sets of
doors off the platforms at quiet stations, the idea of having whole
carriages not on the platform on a busy metro packed with many foreign
visitors is ludicrous

That's a complete non-argument. After having been caught out once, the
foreigners will avoid the end-coaches for the rest of their trip to
London. Simples.
