Please not in World Showcase! At least, not right away- they just don't have the space to handle the crowds.
Epcot is FULL of empty buildings. Put A&E in one of those, where there's ample space to meet up with the crowds. Do the m&g in the old Wonders of Life Pavilion and put a skating rink in the middle. (Disney does bowling with Splitsville, so why not an A&E skating rink?) Let Club Cool be part of the entry display- it's always freezing in there, and the $$$ from Coke might help fund the pavilion.
If you really want A&E in WS, wait a bit. Maybe once the hype dies down, put them in a Frozen meal in Akershus, but restore some of the Scandinavian foods and feel. And update the movie at the end of Maelstrom!
Or move them to HS. Anandale is a fantasy town anyhow, so why do they HAVE to put them in Norway?
