It might load up with a good SWR, but will it radiate? I know the discussion is about base antennae, but when I was on 6M FM, I tried using Antenna Specialists, DB Products, and Larsen base-loads for 42-50, and each's performance was dismal when compared to a quarter wave whip. As I recall, even an LM-150 cut for two-meters worked better than the the 42-50 base loads. If it was easy enough to modify the coil, I'd try do that and keep a longer radiator.
