it's not worth it. Every shred of evidence we've seen regarding forkroot supports that Egwene would not have been able to channel more than a trickle at the time Silviana took over her shield.

You want to believe Egwene went from unconscious to full power in a matter of minutes, despite every other instance of forkroot proving that is impossible, go right ahead. Not to mention the fact that Egwene's doses of forkroot last for hours each and are much weaker than the original dose.
