The thing driving me crazy is actually pretty simple.
Its same as any ordinary SE ultrapath sitting on CCS.
CCS impedance forces all power ripple to appear in
full at the cathode. Split tails doesn't change this
simple truth for the common mode impedance.

The proper solution is probably the same too. Add
ripple to the input signal to make them common.
Loftin White is one plausible example how it could
maybe work...

Either that, or have to filter ripple till there simply
isn't any... Or make a regulated ripple be the input.
That approach should certainly qualify as bizarre!

I mean, like if you left the grid and gate at ground
reference level, and drove the supply ripple instead.
The ultrapath loop would thus be forced to circulate,
because transconductance is purposefully not the
same on both sides. Yeah, go figure...
