It is tempting to extrapolate from the small, light and expensive in racing to cruising. But weight, volume and cost consciousness make this a difficult proposition; The state of the art of a "cruiseable" foiler is the G4. It did capsize with sailing champs on board, it costs 1M and they leave the bolt on mini galley behind on shore when foiling.
Maybe lowering the bar for using foils to just help stabilizing a boat in uncomfortable waves would be a more realistic goal. Setting the foil angle of attack in function of speed for best L/D would correspond to lowering the effective average wave height. Also the hulls would not risk falling back to the water surface when lift suddenly fails (weed, ...) And there is no need to complicate shunting with the swing maneuvers that shunting on foils require.
