All of this advice has been very helpful. Thank you.
Wayne, You are right, it would be a poor trade to compromise the whole point of having the rig to make having it more convenient.
I have one more concern, supporting the chainplate for the inner. I intend to fasten the inner headstay chainplate through the deck and to the thwart that supports the deck at that point. I have not exposed this thwart yet but expect it to be the same as the rest of the bulkheads. I intend to strengthen the thwart's bond bond to the underside of the deck and the hull with biax and epoxy and add to it if necessary. I am calling it a thwart because it does not continue down to the stem. Do I need to distribute this load that far? I can add knees and thickness to this thwart but a rod to the stem would be inconvenient.
