That math and engineering is wildly beyond me! But one suckypoo downer once you do sequester all that CO2? No planetary magnetic field. In short, scientists think there has to be a convecting, rotating, liquid metal core in order to create a substantial magnetosphere. Venus's planetary core is almost certainly missing one, two, or three of those things. The fact that Venus is extremely hot on the surface (460ºC) is at least partially assisting with creating a "stagnant lid" tectonic regime where no heat-venting plate action is seen. So if the surface of the planet is nearly as hot as the mantle and the mantle is nearly as hot as the core, convection doesn't happen. Wiki "geothermal gradient" for more. Thus no magnetosphere, thus no electromagnetic deflection of the sun's blast. Not a dealkiller, but certainly not preferable if you'd like to move in someday.
