Cutter rigs
This Model, more than any other E-Boats (except the Independence 31 and 36C-which are true cutter rigged boats), has often been set up to sail more or less as a cutter. The boat was always quite fast using a high clewed Genoa (Jib Top/Reacher, etc), and a genoa staysail underneath it. The staysail sheeted along the top of the cabin. The mast should have a tang on the forward face for a staysail halyard-typically halfway between each set of spreaders. Some people have hung an inner forestay there, but this will require some significant work down below-as you must tie the deck plate down to the structure of the boat to take those loads.
The reasoning, IIRC, was that since this boat was not overly close winded to begin with (wide sheeting angles, fat keel, etc.), that using a conventional deck sweeper genoa and sheeting it in tight to point high was not as fast (in terms of VMG upwind) as going with the higher clewed genoa (which by definition cannot sheet as closely and probably maxes out in the mid-high 30's apparent wind angle (whereas the genoa might get you to 29-33 degrees AWA). By keeping the slot open and adding the extra sail area of the staysail the boat seemed to actually net better VMG while sailing slightly deeper angles than the other boats. This set up was more commonly used for distance racing where you make fewer tacks (this is obviously harder and slower to tack than a single genoa). For bouy racing, annd especially now with vastly improved sailcloth, you are still better off with the normal genny.
For cruising, I would do this, and set up the staysail on a furler-using a wire or kevlar luff sewn into the sail. This way, you can leave the thing up if you want, and have the flexibililty of using it is as descibed above with a high clewed genoa, or by itself in heavy air. By using the kevlar luff instead of a fixed inner forestay, you can lower the whole thing once it is furled, coil, and stow it if you want to use a normal genny, or just to open the decks up. You will want a beefy attachment point in deck, as it will need a fair amount of halyard tension.
So, yes,, your boat does well with this kind of set up..technically it is not a true cutter rig, but that is splitting hairs.
Go for it.
