I guess my point is that even after using such tools for years I don't find myself remembering many of the heavily overloaded keystroke combos. Of course it doesn't help that I use a Linux box for development and Mac OS for email and document management... so I'm constantly switching between competing keyboard shortcut systems. I've seen companies offering complete custom laser engraved keycap sets, so that got me thinking that building a really big keyboard, like starting with an old school 104 key with full upper row of function keys and the keypad on the right and adding another similarly sized keypad on the left. I got really psyched up for that keyboard from Art. Lebedev Studio that had the oled key caps but they never were able to get the whole setup to work reliably. I think they're still selling the second generation for some obscene price and given my brief exposure to it I'm not fully convinced it's really comfortable to use for lengthy sessions.
