If my calculations are correct, and assuming the four scale lamps were all 300mA types, then you have two 6.3v heater windings capable of providing 1.8 amp (EL33's) and the other 2.1 amp for all the rest.

I would say it is quite do-able. The EL33 winding for the EZ81, and the other for the EL84's and EF86's.
