My 38 mk2, Imzadi, has a 5’3” nominal draft (with cruising gear it’s probably more like 5’6”) after shortening the keel and installing a torpedo bulb made by Mars Metals. I took 10” off the end of the keel (800 pounds if I recall correctly) and installed a bulb made by Mars that weighed around 1150 pounds.
Allen, Pamlico Sound may even be a bit more shallow then Albemarle Sound. The deepest spot between here and the Atlantic is about 24 feet, and most is less than that. And I plan to go to the Bahamas one of these days, so the original 6’1” draft just would not do. I lost some pointing ability because of the change, probably one or two degrees of apparent wind. I used to be able to sail up to about 29-30 apparent, now it is in the 32-33 range. When I was racing seriously with a good deck sweeper headsail, I could still outpoint a 35-2 that raced in the Pamlico Sailing Club. He outran me downwind, so the two boats were pretty evenly matched. I suspect that the end plate effect of my flattened torpedo bulb (it is about twice as wide as it is high) has some of the same impact on the keel that your wing has. Basically, I’m pretty happy with the modification. Particularly when I am sailing in skinny water (like every time I go out).

I have a C&C 30-2 with a shoal keel, my close friend Richard Stoltenhoff had a sister ship SeaCure with the deep keel, Both boats were race equipped white sail boats. I've sailed both boats and they were well matched in the winds we had on LI Sound. When Richard moved south to the Albemarle Sound (20 foot average depth where we sail, but tight 6' entrance to the creek and docks), he had his keel shortened and a Mars Metal bulb applied. We raced his boat after my admiral decided she didn't want her boat dinged by "ignorant" racers. Although SeaCure remained fast and retained her stability with the bulb, we had great difficulty fetching marks. She just wouldn't point as high as Septima and the extra tacks or overstands just killed us. After Septima was hit by a lightening strike, I had her short hauled and ironically she was placed adjacent to SeaCure on the hard. I looked at both keel stubs and they seemed to my eye to be identical. My lead keel portion however had significant additional longitudinal area. His deep mounted bulb was offset by my wing and stability was very similar. My lateral resistance though was much greater and we could climb our way to a mark without pinching.

Their ability to provide not only a bolt on two piece bulb but the design service to recommend the weight of bulb to achieve the same sailing stability as the deep draft keel is discussed in the article. It has been a very successful program for the company.
