For big beers, sometimes cane sugar is added in place of malt to dry out the mouthfeel. Maybe take out something like c60 and try that in its place? I don't drink much but pale colored beers but that is where I would start. That would help lower your fg as well.
I've done at most 2.5 pounds in a 5 gallon tripel, so I know you can go that high but I wouldn't imagine that's necessary.
