I think BWF merely tries to copy what Tennis has: Grand Slams (SSP events & World Championships) Masters 1000 Events (SS events) ATP 500 Events (GPG events) ATP 250 Events (GP events). In terms of geographical distribution: Grand Slams -- 4 tourneys, with 1 in Australia (can be considered Asia too), 2 in Europe, and 1 in America Masters 1000 -- 9 tourneys, with 4 in the US/Canada, 1 in Asia, and the other 4 in Europe. ATP 500 - 11 tourneys, with 3 in Asia, 5 in Europe, 3 in America (including 1 in Acapulco, Mexico) ATP 250 - 40 tourneys, spread out all over the world. At the moment, Badminton has too few GP events (only 1 in Asia and 3 outside Asia) but lots of European IC tourneys organized by the Badminton Europe. I think some of these might need to be upgraded to GP events with prize money of at least US$50k to attract more interests from Europeans!
