as it appears (based upon what EML says) that the cathode resistor and bypass cap can be eliminated.
I don't see where EML suggests that in your quoted text and this connection does nothing to eliminate either of those parts.
simply put, the cathode connection now sits at 1.25V and if referenced to AC ground you will now have +- 1.25V on either side of this point that are 180º out of phase with each other which in a perfect world will sum to a potential of 0vac showing up at the cathode from the filament heating circuit.

Yes?
The main upside is the lack of need for balancing resistors and/or a balancing pot. But, depending on how exact the "center" tap really is, you might still gain something with a pot on the fils (also possibly since aging may affect this too.)
IMNSHO, the pain in the ass part is needing a different socket and non-backwards compatibility with other tubes of the type, as a result.
Cool idea though.
