Yes, even if they wanted to, making joints which can withstand such dynamic loads, while being small, and lightweight will be a giant engineering challenge.

60t static load, now imagine how big will it be when it walks.

It takes serious engineering. And it's been done.The Dragon, from Zollner Elektronik AG.[1] About a third of the size of Gundam, mostly so it could be transported by road. True quadruped. Best engineering in the giant robot space so far.

The Sultan's Elephant [2] was bigger, but less technically advanced. The headaches of transporting it were too much of a problem. Once your art project gets bigger than what can be moved by road or rail, there's a problem.

The Land Walker, from about 2006, was about a third of the size of the big Gundam. Biggest walking biped to date.[3]

There's also Eagle Prime, which is really a tracked vehicle.[4]

None of the videos you linked to show any robots actually walking.

[1] - the dragon is rolled around on a wheeled platform. There is one clip of a leg lifting, but none of it actually walking.

[2] - The Sultan's Elephant is moved around on wheels. It doesn't walk.

[3] - That thing is "skating" around on wheels, again not actually walking.

[4] - And yet another machine that doesn't walk but actually rolls around on treads.

No, the Zollner dragon really walks.[1] Very slowly, and only one foot is off the ground at a time. Top speed 1.5mph.

The wheeled platform is for transport.
