I've thought about doing this, but I'm not sure how much more effective it would be than drain and fill because your only diluting your 12qts of fluid with 4qts of new fluid each time. With the drain and fill, my math works out to the following, assuming a 4qt drain each time, the following is the concentration of the 'old fluid' at each drain interval:
#1 - 66%
#2 - 43%
#3 - 29%
#4 - 19%
#5 - 13%
I stopped at #3.
Doing it using the bucket would probably still only accomplish a partial flush, unless you run until its clear, as the new fluid would get mixed with the old as soon as it runs into the transmission. Based on the numbers above, you would need at least your 5 gallon bucket full of new fluid to get a full change, if not more. Based on my cost of $25 for 5L, that means its $100 to get a full change.
Not sure I was really clear on this, if the above seems to be gibberish, let me know and I'll take another run at it.
