You''ve thought this through and are probably right on both counts. For the "storm" heaving-to, you probably want much less sail area than a large genny, so a smaller working jib or even a storm jib would be good to carry if you''re going cruising. Even if you could get the backed genny to balance somehow, it''d put an unneeded strain on your windward shrouds and spreaders and may chafe the sail to death. Maybe you can get a roller-furling arrangement where you just leave a "handkerchief" of the genny showing. As with all heave-to''s, you have to experiment with main, traveller, tiller, and jib settings to get the balance.
Then there''s the "just hanging around jogging in place" heaving-to in fair weather, while you''re having lunch, figuring out a chart, or whatever, or just because you like it. There, you just might get the genoa to work, at least in light air if you bring the main in more and put the tiller more to leeward, and the chafe wouldn''t be too bad if you don''t do it for long periods. If not, then you''re right, the genny may simply pull your center of effort too far forward for the main and tiller to overcome it and keep you on course. That''s why a roller furling arrangement might work in light air even if it doesn''t in heavy air, you can reduce the jib area as much or as little as needed for balance.
Other than heaving to, the only other stopping techniques I know of are luffing, anchoring, or just sails-down drifting, but none of these will keep you on a desired course.
Best of luck in your sailing and your new boat.
