I wonder if it theoretically would work to kill the DO with the Choedan Kal, or at least close the Bore with that Power.

Rand says at the end of TGS that he has enough Power to Unravel the Pattern, which probably means he is as powerful as the DO, if he would completely break free.

Also some AS in the AoL and Lanfear believed that at least both Choedan Kal together had enough Power to challenge the DO or the Creator.

RJ confirmed in a Q&A that one could theoretically kill the DO with balefire, but it would destroy the world.
Q: Why doesn't somebody just balefire the Dark One?
RJ: The quantity necessary would destroy the world.

So, do you think that it had been actually possible to kill the DO (or the Creator) with the Choedan Kal? And if that is the case, wouldn't it be also possible - as a minus - to close his prison with the Choedan Kal at least? Or would any of these actions automatically destroy Creation?
