A new type of spritsail-like rig ?

A spritsail rig with a jib, but with the spritsail cut diagonally in two along the sprit pole. Now we come up with three sails, a jib, a fisherman sail, and a main. Have you seen anything like this? I cannot see any obvious disadvantages, and it is simpler than a staysail schooner.

Leakage through the cut, around the sprit. Another solution to the poor shape of the spritsail is a wishbone boom.

I imagine the sprit pole as a fixed raked mast, so there are five possible advantages:

1. The two triangular sails, the fisherman sail and the main, can be reefed easily on two in-mast rollers, just as in a staysail schooner.

2. The AR of the two triangular sails is now higher than the original quadrangular, and there is an additional slot effect.

3. A raked main behind a large fisherman sail is perhaps more efficient aerodynamically, and it can work quite well without battens and a boom.

4. Due to the raked sprit-mast, there is no need for a high-roached mainsail and runners.

5. The shrouds of the two masts can came to the same two points on the deck, so there is only one strong-cross and the whole rig can be easily tuned and tensioned fore and aft with the aft stay.

The curious think is that, as far as I know, something like that has not appeared somewhere sometime. The absence of runners and the easy reefing of such a rig are great advantages. What I proposed is essentially a hybrid of the two-masted staysail schooner and the spritsail barge that should have been tried before!
