The beam of the Mk I is the same as the beam of my Mk II at 10.5 feet. A high cut clew will help but the sheets will still chafe hard on the life lines under some points of sail. My boat has inboard genoa tracks but there is a limit on how close you can sail to apparent wind angle (point) and still be fast from point A to B upwind. You will be able to sail higher in light air, say below 10kts apparent but as wind speed increases footing off will pay off. The design mainly because of keel and hull shape I believe does not point as well as some newer designs. Besides the lifeline issue you need to consider the shrouds. The Mk I has for and aft lowers with not much distance between the uppers and the toe rail.
