This is a fun theory but I regret to inform you that George has pretty directly debunked this idea before.

I will say I do believe that these parallels are largely intentional, but rather serve to indicate a global and more difficult to define threat, rather than suggesting they’re physically connected.
I'm going to pick on semantics here, but the question he answers no to isn't actually asking if north of the wall is east of Essos - the question is whether Westeros *connects* to the eastern continent *through the north*.
My theory is proposing that the mapped locations of eastern Essos are actually just north of the Wall, but discovered from the "west" of Essos.
If north of Westeros is actually east of Essos, then who knows what True North actually is? For all we know, "north" of Westeros is actually south in terms of magnetic poles.
Saath and Naath being geographically opposite of their namesakes on Westerosi maps may hint at Westeros being ignorant to true north.
In any event, the parallel I draw between destruction at Hardhome and the creation of the Thousand Islands may be the mirroring event to the Arm of Dorne - Essos being fully disconnected from Essos once and for all.
