Wiring the output tubes in triode will lower the open loop gain of the amplifier by lowering the gain of the output tubes and this will lower the amount of FB without doing anything else.
I wouldn't remove all the FB. Pentodes wired as triodes are not linear enough to operate without FB. The harmonic distortion will be too high.
