Agree Pace, but their are light twins and light twins.
The Seneca, Seminole, Duchess, Couger and Partenavia that I flew, I would not want to lose an engine at or near MTOW. They were pigs for climbing at blue line and your suggestion/s would have been a go'er.
The C310, C421, BE58 and KA200 are a doddle and will happily climb away at blue line.
All horses for courses.
