I wouldn't go so far as to say 'a lot of weight.' I can see this getting into the mid to high two pound range. That's, at most, a 1lb saving for the entire robot at the cost of significantly increase machining time. As drawn, the plates could be made on 195's EDM, if you add pocketing that significantly increases manufacturing time and adds another machine. (unless it is already being milled, then it just adds time)
If that middle plate can be eliminated though, that would save weight and make it easier to machine (one less part). I can't really see what that plate's purpose is so I don't know how easy that would be.
