are you asking if anything comes close? or just talking out loud? cuz what you want will never happen, especially once you mentioned ergo. don't understand your modular design, as you linked the TE, which doesn't have an ergo keypad, just a "programmable" switch one, also the TE is like less than 104 keys, just a bunch of fake keys, really if you want ergo, just go kinesis. Take out the ergo requirement and you can find a few that sorta work.
