Coupling a Dyson-Harrop satellite with a huge array of magnets might do the trick. Depending on the density of the Solar wind on the day side of Venus. It could be as small as a few miles in diameter. Focusing a proton beam into the Venereal atmosphere should result in some hot water and Methane as the H+ reacts with the CO2 at high temps.
