Additionally, without knowing more about the "fiberglass extrusion" I'd be concerned about creating localized stresses in the hull, which could result in cracking. Will this extrusion expand and contract with temperature changes at the same rate as the composite hull? If you strike a rock with the new keel, how will that effect the hull?
The Magic is a wonderful hull for it's intended purposes.If lack of stability is an issue for you, perhaps some instruction would be helpful. Learn how to get the maximum out of the hull, as it is, rather than try to make it into something that it isn't.
Another possibility is that the seat is mounted overly high. I've seen folks raise seats considerably, often for greater comfort, but at the expense of stability.
