I enjoy chatting about this stuff. No need for thanks here. I appreciate your sharing your secrets so I can see how much I'd like to try myself.
Imagine your transformer in place of the common mode choke...This is what I was envisioning Note the Y caps orientation with respect to earth. It might be worth playing with to try and increase impedance to common mode noise.
Though, regarding your filter schematic, I haven't seen anybody using an inductor on earth that way leading me to wonder what it's function in the circuit is. Presumably it can't do much until there is appreciable earth current which in my locale is strictly forbidden above a tiny level.
With double insulated, tinyish transformers, even the authorities presumably wouldn't have any problem with you not using special safety rated parts.
