Yep, continuous ridge vents at the ridges and intake opening within 3' or so of the valley discharge. That will give enough vertical distance for passive convection. Problem with this approach is the expense. You'll be re-roofing and it would be best to move the insulating envelope to the underside of the roof. Quite an undertaking.
If the budget is tight, I still feel that the sidewall louvers and mechanical ventilation is the best option. It doesn't require messing with the roof and it shouldn't require much additional insulation work. Just need to find the "trouble" areas, ensure air sealing and thoroughness of the insulative envelope, and install the louvers. The whole job could theorectically be done in a weekend, providing what I'm picturing as existing actually is existing.
Life's too short...so enjoy it!
