If you don't mind programming in Forth, there are stack soft processors that
scrape the bottom of the cost barrel. They reach a LUT usage level where
you can use several of them assigning separate tasks to each one rather than
worrying with multitasking.

A well presented and through review.
Would like to mention that some of the FPGA soft core processors
have an incremental cost under $1 and have full tool chains:
ZPU and some versions of RISC-V.
Many of the legacy processors not mentioned by Jay Carlson also qualify (soft-core version with under 1K LUT count: 6502 ...).
