What legal requirement is there for a low level / slow asymmetric cut?
Restrict inflight asymmetric ops to high speeds and altitudes. Then if there is no simulator on type, then as Centaurus suggests above, do the V1 octopus dance in a different sim. Metro, king air, Saab, Sure they’re different, but they yaw the same way, need the same type control inputs to keep it straight etc.
In the real world every engine failure is different, based on environmental, engine, loading etc. As such you’re not training nor checking to assess a perfect sequence with x degrees of rudder input and y degrees of aileron - you’re seeing how the pilot identifies the unexpected situation, assesses how much input and adjusts accordingly.
I’ve heard of at least one operator doing it this way on a turboprop with no sim.
