A couple of weeks ago I did a roll of Tmax-2/400 in LQN at 1:40 in semi-stand. 70 degrees F, 50 minutes total time with one inversion at 25 minutes. Negatives came out fine, though I could see signs of bromide drag on the overexposed film leader but not on the images. Given that time is not too critical for semi-stand, you could try this technique. If I were to do it over again, I think I'd gently agitate around every 8 minutes or so rather than go out to 25 minutes.
