I'm not sure if I understand. You want a tool that would examine a system and produce the minimal kernel config that would cover all the system needs?
First of all, it's a chicken and egg problem. I'm not sure if you can discover certain system capabilities if the kernel doesn't already offer support for that capability. So you'd need a "full" featured kernel to produce the leaner one.
Second, some hardware is pluggable. USB printers, for instance. There's no way for a diagnostics tool to realise you need USB printer support unless you have one plugged in and turned on at examination time and if, again, you don't already have support for that.
So I'm afraid that in the end the human is needed to project everything that would be needed in a kernel.
