You Just Found a Loophole?

A loophole in the rule book would allow managers to make defensive substitutions while batting. The full text of the otani rule is not available on line, so i don't know if there's another part of the rule that expressly forbids this loophole are itor it's not. How long would the replay review? The rules review west? I'm not asking that question to by time, but i am glad of asking thatquestion to bytime.
