Sure it can work, but you don't need to add a third brush to make a 6 volt genny charge at 12 volts. In fact, depending on the location of the third brush relative to the fixed ungrounded brush next to it, you could have LESS charge then if it remained as a 2 brush where there's less resistance and voltage drop between the 2 brushes. The third brush are the older system gennys where charging could be limited and regulated by moving the third adjustable brush further away from the fixed brush. A genny dont necessarily know what its output is supposed to be, it increases if it turns faster or you pump more current through the field windings. Regulating field current is what a voltage regulator does.
I have converted 2 brush 6 volt gennys to work at 12 volts simply by using a 12 volt voltage regulator. Don't anyone have a calf, I'm NOT saying it set the world on fire or charged at any high rate, I'm ONLY saying it worked. One potential problem with what I did is the field windings may be passing more current then they are rated for, that's why if a genny shop converts 6 to 12 they would change out the field windings to those with higher current rating. However my conversions (left old 6 volt fields in place) worked and never failed even if tis NOT engineering perfect or correct.

Today's Featured Article - The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
