But now that you make known your real desire to extend a bus and have some
registers to access, an FPGA solution is plenty viable. Thinking that you
needed a bi-directional connection with no sense of which end is driving or
receiving as you stated in your original post is a completely different
problem.

In any case, extending a bus is easily doable in any FPGA that has enough
I/O pins and meets voltage standards of the things that it is connected
with.
