Those tubes have wildly different heater ratings.
The 6922 draws 0.3A per tube, the 6SN7 draws 0.8A per tube. You need to start thinking "What if I burn out the heater winding on this power transformer" before you go all "lets hear the sonic differences and see if we want to keep 6SN7s in there".
Really, the power transformer can probably take it, but any temperature rise is just eating away at its life. I would not recommend it.
