Update for everyone still following this: I added 60 oz. of canned pumpkin (60 min. boil) and 1 tbs pumpkin pie spice (2-5 min boil). The OG ended up as 1.064, and the FG ended up as 1.016. Strong pumpkin taste (haven't bottle conditioned yet, will do so for 1 month starting today), but not overpowering of the grains. Very enjoyable to me, although my favorite part of autumn is tasting all the new pumpkin beers...I just love them. Just thought I'd let everyone know what ended up happening.
