That's what I'd like to see happen. Edward goes to India and tells the locals "listen to me, your Emperor, and India shall be independent!" Maybe, just maybe, the Indians might be receptive enough to recognize him and force the Raj's hand ...
Add to that the unusual implications of India having a "foreign" Emperor.
Maybe a revolution in Britain? Or an (unlikely?) occupation even?
And an earlier ascendency?
Assume he forges political ties with (local) rulers in India, and when the
fecal matter collides with the ventilator he casually packs his stuff and moves to the crown jewel of the British Empire, declaring it independent?
One of the ideas that crossed my mind are a socialist/fascist "revolution"/uprising in Britain, or a "worse" (for Britain) WWII, that ends up with either said revolution (during or after WWII), or even occupation(and the propping up of a puppet government).
Obviously this would require either an earlier ascendency (and more shenanigans) and/or him not abdicating (as early) as he did OTL.
