Great discussion although I always pointed out to students converting onto twins, the only certification requirement was 1%climb gradient at 5000' ( along time ago so the numbers might not be entirely correct). EFATO was best handled by looking for a clear space ahead and controlling it to the point of impact.
A further discussion might be what is actually causing light twins to crash?
CFIT, fuel exhaustion, EF in cruise. Possibly a bit more focus on those areas of piston multi operation might be worthwhile.
