In a way, that's part of the point of the Cutwaters. You get a sofa-like environment with the table in the forepeak which is pretty cool.
Having had truck slide-in campers, this was always a tradeoff. The standard dinette with a table that lowers and then you put the seat back cushions on the table has always be the typical setup. But, about 10 years ago, the "jack knife sofa" came into fad. They run around $500 and are available in 60, 62, 64, 68, 72, and 76" lengths, Flexsteel is probably the best known manufacturer:

No cushions to move or arrange. Huge storage under the couch, usually. You lose the seating of a U-shaped dinette, and instead of a squarish table, you use a long narrow table that mounts on two removable cylinders. Hiding the table when using the couch in sofa or bed mode is always a problem; I've hinged the table to fold to make it easier to stow. Roof top storage in a pod on our sport rack might work.
Of course, the fiberglass forms under the seats probably precludes retrofitting such a couch. But some of them come without the storage unit/box underneath and are quite thin in the seat which might allow mounting on top of the fiberglass supports for the present seats. However, they you have all that fiberglass still sticking out in front of you. If you could remove the fiberglass that currently holds up the seats and forms the top of the mid-cabin enclosure you could install something like this:
I think, the easiest answer might be to change over to a Cutwater as I don't see the factory losing the dinette/midcabin design soon.
