Everything you have written up to this point has been in a future tense, "Herrmann would get...." or "Herrmann could ... ". Obviously in said future world there is no Thomas or Komatsu. So now you're taking ABs away from a legitimate OF prospect.

Until that time however you're still at ~100 ABs.
B: I am not "taking away" anything, but I have some reservations about repeating the very good health of Mauer, Willingham, and Doumit. I think Willingham will likely DH a bit more too, anyway.
To what end? We already have Mastroianni who is almost perfect in the 4th OF spot.
C: It is possible to think of Herrmann as the LH 4th OF.
Again, neither of these has happened yet so they are moot points.
D: One scenario that I don't like, but might very well happen is that the Twins trade Denard Span. In that case, the primary OF lineup looks to be Willingham-Revere-Parmelee. Late in the game, defensive subs of Herrmann and Mastroianni would likely be wanted when the Twins are ahead. This might not mean a plate appearance, but certainly some innings played.
E: If Morneau is gone, this clears up more DH time for Doumit anyway, so I would expect more catching time for Herrmann because of that as well.
You think that 8-12 extra hits over the course of the season equates to 1-2 more wins? I would be interested what the WAR guys have to say about that. I personally doubt it would come out to even 1 win from a probability perspective.
F: So, I will play kind and grant you only 12 more trips to first base. Now let me ask you this, is 12 more than 0? Might a couple of runs end up meaning 1 more win, or even 2 wins? Isn't a 1-2 win difference actually significant when talking about the 24th or 25th roster spot?
Right now the Twins 3rd catcher is only going to get ~100ABs next season again. When you're talking about 100 ABs it doesn't matter if that catcher is Butera or Herrmann. The amount of opportunities combined with the small difference between their hitting acumen is such that they will have little to no effect on next seasons outcome. If the number of ABs meaningfully changes then this becomes a valid discussion.
