I will have to claim ignorance on exactly what the secretariat is doing with options. What you've just suggested sounds like a very reasonable way forward, but I've heard from the Minister of Public Works in open press that the statement of requirements will be set aside as the secretariat does its work.
At a point in there, of course, the Canadian armed forces will give us advice in the form of a statement of operational requirements and any advice on any options that come forward, and that will be our role.
