Looks like a lot of thought went into that board, nice work. On my b22 I will give Assemblycrafts BLD boards a go. They use DRV134/THAT1646 chips for the conversion, hopefully it will work ok. Im not shooting for tranformer-like performance, just an option to use SE input when needed.
Also, I remember Amb recommending me a heavy duty relay to switch speaker outputs. What relays are you using for that?
