Its a fair point but would the effect be as great as it would be on the legs?
You're getting in finer points of skeletal mechanics, far beyond my ken.

As everything is a trade-off, there would be a fair spread of possibilities. I can only guess at the boundaries. Hal Clement's Missionr of Gravity assumes that, at some point, the only body plan possible would be a centipede, if I remember correctly after all these years.
