Interesting idea and could be a lot of fun for this group. As far as hoping it would be produced, the problem with writing a good spec script is once Hollywood gets its hands on it, it will change. It will be curious to see what (if it ever gets done) the new producers come up with.
Good drawing of a Robby upgrade. I assume that internally, his 1956 small vacuum tubes, germanium transistors, Nixie tubes and neon display have been replaced by LEDs, multi-core CPUs, GPUs and TPUs (all as a SOC) as well as a 5 Tb SSD? For vision, the upgrade from videcon tubes to CMOS image sensor means much improved resolution. Unfortunately, due to the sensitivity of modern solid state electronics, any illegal orders that cause the display of electrical bolts will probably permanently disable it.
All kidding aside, one of the strengths of the original was not showing the Krell. As Morbius (Walter Pidgeon) points out, the only clue as to their form was the door shapes. For 2001, Kubrick tried a couple of ideas, but in the end couldn't come up with a throughly convincing alien. Plus he was way overdue on the date for release.
