That's exactly what I'm doing (and tried to discribe).
And true, Cairngorm doesn't "require" 1-to-1, probably should have made that
more clear :)
But if you look at the docs and samples etc.. they do advocate it that way
(well at least last time I looked into Cairngorm).

Actually, Cairngorm does allow arbitrary mappings from events to commands,
it does not require 1-to-1.
The FrontController's addCommand() function takes an event name (String) and
a Command class. In our app I have used the same event with different
name-constants to run different commands, like so:
addCommand(FollowingEvent.ADD, AddFollowingCommand);
addCommand(FollowingEvent.REMOVE, RemoveFollowingCommand);
In the constructor of FollowingEvent I take a "type" (String) parameter
which I pass through to CairngormEvent's constructor.

And one more thing I dislike is the 1 on 1 mapping of Events and Commands.
From what I've seen in their docs and samples they use a different Event
class for every Command, which IMO makes no sense.
GetUserEvent
UpdateUserEvent
DeleteUserEvent
CreateUserEvent
And the static constants are stored someplace else, can't remember but
think it was the Controller (that extends FrontController).
Rather than having 4 Event classes for each Command I prefer 1 Event class:
UserEvent
which has as many static constants as required:
public static const GET_USER:String = "getUser";
public static const UPATE_USER:String = "updateUser";
public static const DELETE_USER:String = "deleteUser";
public static const CREATE_USER:String = "createUser";
Again this is inline with what is already present in the Flex framework:
MouseEvent.CLICK
MouseEvent.MOUSE_DOWN
MouseEvent.MOUSE_UP
etc..
