I am still wondering if the cost is going to be that high: If we can
emulate more of the existing components in the FPGA then we will save
some cost on these. Your observation of the serial port is just one

OpenCores already have one:

A thing to take into account: All the ideas does not have to fit on a
FPGA. You can reprogram the FPGA in about 10 ms. So you can have
different sets of "devices". So four sets of functionality you do not
use at the same time, say,
You cannot use them simultaneously, but you can change set in 10 ms.
