Is it correct ? What do you mean by "free style"? A user-defined style that isn't derived by rules or a context? It seems to me that you want to mix context-based styling and per-feature user-defined styling. What about that: when user wants to modify a feature's style call createSymbolizer to get the feature's current style, modify the returned style object as requested by the user and store it in feature.style. There may be other options, but this is the one I see at this point.
