The amount of movement you indicate is excessive, I agree, and the cross-braces might be the only solution since I would image the lag bolts are tight and things are still moving. I think that the cross-bracing will be most effective midway on the span of the legs that are moving, (like your 1/21 picture) although that might not be the most aesthetically pleasing location. If you could somehow apply the cross-bracing at the innermost section of the curve, that might be the most invisible and still provide adequate support. Again, you could test this by moving your clamped pieces down to the apex of the lower curves. Looking forward to seeing your final solution.
