Unfortunately, not yet. There was a proposal made during the review to
allow states (including submachines) to be cloned from an existing
one, but it is not implemented yet.

You can call get_state<my_submachine&>() on the outer fsm (at best in
the entry behavior). For example:
struct Playing_ : public msm::front::state_machine_def<Playing_>
template <class Event,class Fsm>
void on_entry(Event const&,Fsm& fsm)
