I'm not familiar with the FPI scripting in FPS Creator as I have never actually used it in depth, its something on my very long list of things to do. But can you not just make that entity change it's position to the X,Y,Z coordinates of the enemy character when it is is killed and then spawn it.
If this isn't possible it may be something to recommend to Budokaiman and he seems to be the FPS Creator X10 developer now that Lee isn't working on it, it really can't be that hard to add in some commands to move an entity using coordinates.
