You're right, Winky was not a true light heavyweight, but he was still a very tough opponent.
Calzaghe isn't a natural light heavyweight, but an unbeaten Calzaghe is a tougher challenge than any 175 pounder out there. I think Hopkins is a worthy light heavyweight champ.
If Hopkins beats Calzaghe and wants to keep fighting at 175, and Dawson beats Johnson, then Hopkins-Dawson would be a legit fight.
