In theory the phospholipids Reverse uses to do this would halt the development of male flowers, or at least significantly inhibit it in a strictly male plant. It might be interesting to see what effect this would have on a purely male plant but it certainly wouldn't make it female.
The way it works on hermies is that it uses particular phospholipids that prevent the male flowers from maturing, but leaves the female flowers alone. So you wind up with the outward appearance of a strictly female plant. If it works just as well on a purely male plant, the best you'd get would be a plant that never matures. So kind of pointless except just to see what happens.
