as of today, june 21st, is there any conceivable way you add liquidity on bats, and receive anything less then .0024 per share?
Yes. Go into a cave, and you will get lots of liquidity from the bats. It makes an excellent fertilizer
The fee depends on the order size. Here's a copy of BATS' fee schedule: http://www.batstrading.com/subscriber_resources/BATS_Fee_Schedule_20080601.pdf The fees for hidden orders are at the end.
but basically, per the schedule, it would be impossible for me to receive a rebate of .0022 per share.
