If I see it clearly, you don't have a drain plate... I assume it will drain through the holes on the agitator.
I wonder where the pipe resides?
I personaly wouldn't dare making more holes through the agitator.
1. if it's like many, this agitator is a bastard to remove!
It is sealed by under, so if you unscrew the cross screw on the top, the agitator will not move up as it would be expected.
just try and see.
My guess: it will not cause any problem
for top mod questions, ask Mohican, he did some marvel on his new boldtbag machine.
He surely could give you some good hints
