Small unvented soffit area
The front elevation of my home contains a gable roof area that protrudes less than two feet from the main front wall. There is of course a very small and isolated soffit area on each side of the gable in this 2 foot protusion, that is purely for design as it contains no soffit vents. The gable contains a ridge vent (as does the rest of the attic) and a gable vent. The attic area above this gable area is common the the rest of the house attic, which has functioning soffit vents and baffles.
One side of this protrustion exists next to the front door and frequently this very small area of roof suffers from ice damming. The ceiling in this room is a 12 foot flat ceiling in the center of the room, with short slopes dropping to the 10' plate line on the sides. Therefore, there is a very short run of "cathedralized" ceiling leading to the flat attic above. This cathedralized area is against the roof deck and contains R-30 batts with no baffles since there were no eave vents to baffle.
Obviously there is air leakage leading to the ice dam problem, as well as an inferior level of insulation in the flat attic area (amazing that attic areas that are difficult to get to are often under-insulated compared to easily accessable areas!) I can take care of the air sealing and adding additional insulation in the flat attic.
My question is this: Since these very small soffits are non functioning, can I dense pack that soffit area along with the roof side slopes? Some of the R30 batts in the sloped area have been damaged by critters in the attic previously, so removal of the remaining batts will not be too difficult.

I will not be able to finish my deck for months but would like to get a final inspection signed off.
