Particularly the showerhead in the far corner and the false bottom only covering a small section of the bottom, in regards to its ability to rinse grains that are in the far reaches of the cooler during a fly sparge.

I'd be cautious of the round false bottom lifting up on the square bottom. I used to have a 9" false bottom for a 5 gallon cooler, upgraded to a 10 gal cooler and because the false bottom didn't extend to the edges of the cooler, I got a lot of stuck sparges. I upgraded to a larger false bottom and no longer have those problems.
