Will, On all the pianos I carry, there is a steel beam going across the keybed to stabilize it. In fact on some of them the lyre is mounted to the steel box beam. I do think that an alternative might be satisfactory and have thought of building something of 2x and plywood but have hesitated on how to mount it temporarily without making additional marks on the underside of the keybed. I've moved without the lyre but comparatively it is quite difficult.
