Nathan,
The Critical Text supporters are not big on what you are asking here. They can't be. They tend to believe that manuscripts is where it is at, and that the older the better. Therefore, they are always looking for another motherload of manuscripts to surface, so they can further tweak the Holy Scriptures. They don't believe in a stable text, or that the church always had the pure word. For the CT people, having the word pure for say 95% is fine, the rest can be questionable or different.
Basically, the CT promoters deal with the Scriptures just like they deal with any other ancient writing. I have yet to see credible arguments from their side how God superintended the preservation of the scriptures and at the same time deal with the fact that God's pure word was hidden from the church for well over a thousand years.
