If you're looking for a layout similar to TKL boards with MX switches, that might be your problem.
There are also quite a few asian-made boards with clone Alps, but I'm too lazy to find them.
PS: I also would of liked to have a Filco/Ducky TKL Alps board as a cheaper alternative to buying a custom board. Those boards are great to transfer keys out of those darn single unit backspace Alps boards.
