today you can logout and click back to change the bnet sub account to end up in the right slot? (without a full reload or changes to accounts that are already in the right spot)

this being said, vfx non withstanding, in theory I could add some feature to swap slots (right now I map actual logged in character to it's current slot# but I suppose it could also swap some slots... the problem I guess would be how to configure that / UI wise)

maybe 2 tables and you drag reorder the slots?
