MBehave: I do not want to be that guy, but no, it simply will not work, not with current science, probably not ever.
First off, feet size vs tracks, the ground pressure on tanks tracks is actually lower than humans, this really does not matter that much since the area absorbing the TOTAL weight can't handle it.
The classic example is a bridge, you can march a million humans over the bridge, but not a single 60ton tank, despite the tank having 'lower ground pressure'.
Second Those feet are gonna have to be articulated and handle those kinds of weights, for a mecha to work it needs to have that on a single foot, or rather a portion of a single foot, as anyone working on groundpressure in human running will tell you, it's not even close to being equal pressure spread out under the foot...
Third ground pressure on a bipedal system goes up as you increase speed, mech running will have shear pressures high enough to rip steel to pieces, we do not have materials capable of handling those kinds of forces.
Fourth, Armour, specifically 3 dimensional surface area will be much greater as compared to ordinary tanks, this leads to higher percentage of weight/protection levels, there is no way around this one by the way, short of forcefields?
fifth: We do not have a viable propulsion system for practical mechs.
So yeah mecha are cool but we do not have the science to make them even impractical, at this time they are a bad joke.

Bottom line: Power armour are an engineering problem, mecha a science problem, and nothing short of handvawium will give a mech anything another shape can't do better.
