Yes, this would be good.
But working within Keyboard Maestro as it stands, I think I have a good working method that possibly helps with your question.
I try not set two triggers for the same Macro but to make an Alias of the macro and give the Alias the second trigger. That way I see the two triggers in my macro group list and if I alter the Macro the Alias updates too. I can even rename the Alias to more closely match the mneumonic of the hotkey.
Here is an example. I have a folder called "Recipes" with recipes in it. I have a Keyboard Maestro Macro to take me to that folder when I press a hotkey. The folder "Recipes" is in a folder called "Instructions" so, sometimes I press ⌃⌥⌘R to run the macro (which gives me the Conflict Palette of all folders beginning with "R") and sometimes I find myself pressing ⌃⌥⌘I (which gives me the Conflict Palette with all folders beginning with "I"). All to get me eventually to the same Recipes folder.
So, I make a Macro called "Recipes" and give it the shortcut ⌃⌥⌘R. Then I make an Alias of this Macro in the same Macro Group (Edit/Make Alias). I give this Alias the shortcut ⌃⌥⌘I. And the nice thing is I can rename this Alias whatever I want so, I call the Alias Macro "Instructions/Recipes".
I find this is more powerful than just giving the same Macro two hotkeys - as by renaming the Alias it will list in the Conflict Palette according the name I have given it. And I can see the two hotkeys listed in the Group of Macros.
Hope that makes sense! Easier to do than to explain.
