I don’t think it would be impossible, but there’s nothing OOTB in Windsor to
support such scenario, mostly because it would be non-trivial to provide a
generic solution.
But, if you keep track of IExceptionHandlers you register it should be fairly
straightforward to then pick the right one and resolve it by name using
ITypedFactoryComponentSelector
