You know how some things work BECAUSE they're small? Ex. Bugs work because they're small; Upsizing them to be as long as a human is tall would result in their knees being broken and their carapaces being cracked open under the weight of their internal... organs?
That hip assembly works on the NAO because the NAO is relatively light. Upscaling that to be on a 20+ ton machine would mean lots and lots of scrap metal before the 'Mechs even step out of the factory. That, or you super-size it to be able to withstand the burden of the 'Mech and suddenly you've got the classic "need a bigger engine" scenario (you know, the one where your vehicle needs a bigger engine to move, but putting on a bigger engine means it weighs more which results in needing a bigger engine yet again... etc, etc).
