If your PA works OK at 2500 volts with full rated current it'll
likely be just fine at the higher voltage, although tank losses will
increase (especially on ten and 15 meters).
That's because the loaded Q will increase under the guidelines you
gave.
Watch those component ratings. That extra HV is tough on parts,
especially if you get the PA underloaded.
