Since you have the CT xformer I'd probably ground it and one connection for heater... This is the arrangement in UHF converters I've repurposed into xmitt... Also I have a xfomer from a GE remote speaker xmitt, it has a CT on the 6v winding with each side of heaters fed separately...
Honestly I'm yet to see a difference in either method, unless one of the tubes has H-K leakage you won't... In the event of H-K leakage, the CT ground version with each heater fed separately should be better... Of course unless you were using 12v tubes, impossible to do so in this application... Well not impossible just not practical...
Of course you could use DC on heaters, again not really practical but necessary when using oddball TV tube.
