And don't forget to consider if the prop can be feathered. Just an aside... remember light twins single engine performance numbers are based on *density* altitudes. On a hot, humid day at higher altitude airports lose an engine and your only option to maintain Vmc is a descent to a controlled crash.
An accurate model would be a real plus in this area to demonstrate just how slim the margin is for light twins.
