i don't think so, because that would be a bit absurd of Roger. also, that would mean that Shanks spent more than a decade in east blue (Roger died 24 years ago and Luffy's childhood was 12 years ago) which is abit too much for any journey Roger would go through (keep in mind that including the first and second time it took Roger to cross the grand line it was in three years)  and inuarushi mentioned that the WHOLE crew split after the grand line and then Roger turned himself in, thats why not all of them were there at the excution) Buggy and shanks were there though and that's where Shanks started his journey (i would say it took him a few years to  gather a crew, hit the grand line again, then come back.) when he lived in east blue he said that he still had a few journeys to make before going NORTH which is again in the grand line i guess he wanted to became stronger for him& Luffy to meet as an amazing pirate so he (Shanks) became a yonko therefore residing in the new world.
