My problem wasn't with Harry being the mastermind, but the general execution of the mini. It didn't deliver on what it advertised (like I said, it seemed like a stripped-down, speed-run version of the clone saga we got, with some minor plot alterations... rather than a daring different take on the saga that truly distinguished itself and justified its existence*). I agree that Harry could have worked as the mastermind. However, I think Harras was actually right to mandate Norman's return (and I don't take editorial's side often). Although it was painful to retcon his death, Norman has been a boon for the Marvel Universe since his return, especially in the 2000s when he was appearing in Thunderbolts, Dark Reign/ Dark Avengers, Marvel Knights, The Pulse, etc.
I also think PP:SM #75 was a mostly satisfactory climax to the clone saga. And now I can't imagine the MU without ole Norman.
*- now that I think about it, the best alternate take on the clone saga that I've seen was in the 'Life Story' mini.
