Missing important points, are we?

You need to change the Action, since each Action can only be used once. Search to find a list of available Actions.
This might, however, break some stuff like SW-Anims. To make the clone more independent, I think you can use Type=Nuke for the Westwood one, and Type=MultiMissile for the other one. Dunno what's the practical difference between using only one type or two types, but I do know this only works for the nuke, 'cause WW renamed the Type for some reason.
btw: I give no guarantee for the names of the Types. I have no access to my INIs right now.
