if the torque drops rapidly after peaking at any RPM, the HP peak would be there also

Its not very desirable IMO, to seak out such a situation. Easiest way would be to limit the RPM so that the torque curve doesn't peak until it hits the rev limiter. On a NA engine, this would require a really big cam(s), or a really big turbo, neutering the lower RPM as much as possible

But he didn't ask if it was an intelligent thing to seak, only how to accomplish it.
