Not really. Personally, I was thinking about how to solve the operating system and transmission device first, and the weapon configuration is also very problematic. For example, the heavy weapon configuration affects the center of gravity. Because the whole system is too finely protected, it is also very deadly (equivalent to all parts of the human body), such as joints, and this kind of weapon only has certain maneuvering advantages in special terrain, and its practical use may not be high, for example, if it is humanoid, it must be higher than tanks, right? Wouldn't it be easy to find out?
Personally, I think it is feasible to have a single soldier's exoskeleton or power armor if there is such similar equipment in the future. Of course, there may not be a mecha or something. After all, we can't predict how to fight in the more distant future. Maybe the mecha will show its talents in the future space?
