Seems to be the party line here, but yes, cut down the metcons to just a couple a week, and keep them short.
Given that one of your goals seems to be a high-level of GPP, I would suggest alternating periods of lifting/short metcons with CrossFit workouts. You could even make it a seasonal thing.
At CrossFit RVA, we'll be essentially doing this for the greater part of the winter. We;re cutting the length of metcon work, producing shorter, heavier workouts, with plenty of lifting days. Add in a little extra skill work to fill in the time gap, and I believe that everyone will come out strong, fit, and ready for some longer workouts in the spring.
