Interesting; I usually just pass the AddLayersCommand with more or more 
resources (and watch it create the default styles etc…).  

I don't understand your question about "add to an existing layer some 
resources". The layer looks up the GeoResource to use in the catalog; using the 
Style to aid in drawing etc...
