So there's a theory one wishes to prove? And the way one goes about this is to distinguish between scenes of the game as being delusional or real based on what'd happen to fit with that theory?!
...is there anything but the theory itself which indicate that the protagonist waking up in London is canonically the real deal, whereas what happens in the other endings is canonically delusions? 'Cause I'm sorry to say, but if one am using the theory you're trying to prove as the only frame of reference for understanding and sorting the facts, then of course one will get the desired result; Along with demonstrating the intellectual capacity of a hamster running in a treadmill.
Combine it with this theory surfacing in the face of massive disappointment with the endings, and the term "a fanboyish clinging at straws" would seem to describe it best. Not that it's impossible, but absent any official confirmation - either in an official statement or in DLC to come - it's no more likely than me claiming that Shepard seriously wants to screw his mother: Then cherry picking every piece of dialogue from all three games which could in any way be crammed into such a Freudian analysis, and discarding the ones that contradict it with a "Oh, it was just him making yet another attempt at trying to resist the craving I know he has; That's why he pursued that gay romance with another man, yes it was!".
TL;DR: Once you're starting to sort the validity of facts - in casu whether they're delusions or not - in accordance with the theory you're arguing for, then you have no argument at all.
