I agree here, if possible skip B&C entirely for that evening and move the ADR to another day. On both the reasons mentioned; Dessert included at Akershus and the cramped time to get to B&C so soon after. I'd see myself rushing over, while being quite full already and sit there not entirely enjoying the B&C experience to the best. Because it is truly a great place for amazing desserts!
I have gone there after snacking my way around WS or hanging out on The Boardwalk, then treat myself to a yummy dessert.
If later than 9pm and you're still in Epcot WS, strolling to FW's entrance/exit could be quite a nice walk after the crowds have thinned out substantially. And there hop a bus to AoA.
If not keen on walking that way
(i.e EMH evening in Epcot), walk to The Beach Club Resort, still after hours and take a bus to DS and change there to AoA. Or another option is to go to the monorail, travel to the TTC, and there change to a bus over to AoA.
There are a few really nice options to choose from. Be sure that Disney will take you back either way you choose.
But what it all boils down to is... I'd recommend to move the B&C ADR.
