Ha, ha, ha. This is the reason all racing catamarans have a cabin. Show me one ;-))?

I see your goal is long-range sailing. Then, only the original sail area is practical to handle in any sea and wind condition.?

For long range. No open bridge. A simple human aspect. When it rains, you are always on the hull without the loo.
Biplane rig. The rig is not possible without a lot of inside room loss. The masts would be standing in the berth rooms.?

To control the top of a square top is not possible. The rig, as shown, is, in my view, the most practical one for any weather situation.
