No. THAT board has four inputs and four outputs.

This would be a new board, with on-board isolation (transformers) and 4:1 mux switching (four selectable inputs, one output).

The current 4 channel level shifter for B3 is just that. A level shifter. It does no MUXing. The B3 is the MUX in that case. 4 in 4 out + level shifter.

This new modules is more geared toward the B3SE or even the older B2. 4 in 1 out exactly the same as input. No level shifting involved (as that is done on the DAC).

If you want you could make the new module work for B3 by using the single SPDIF level shifter and then not using the ES9018 MUX but instead using the external MUX.

Cheers!
Russ

Consider making the switch function possible from a uP, like the Arduino.

Done. It will use the same methodology as the B3 and the CS8416-based MUX, so that it can be used with the same switch board. For Arduino (or other uC), you need two GPIOs to make a binary selection.

I would love to have the switching done by my AMB LCDuino, but i cannot code C - so i'll probably have to get some help from somebody - if it isn't possible to do by switch like on the old board(s).

It is possible to use the 2-bit switch selector. You would just wire to the new module instead of to the Buffalo.

I'm not entirely sure that I understand options #1 and #2, so I'll just weigh in with the functionality that would make my life easier. Ideally, I'd like to have a single board that allows for up to four inputs (each of which can be SPDIF/PCM/DSD) and one output. Is that even possible? I would like my DAC to support both coax and Toslink SPDIF as well as two different USB modules (Amanero for now, and the TPA USB module when it becomes available).
