Sounds like it could more than halve the atmosphere (from 93 times Earth atmosphere to 43 times).
Though worth remembering that the surface of Venus is an untouched wilderness region containing billions of years of geologically significant information. I'm all for walking around a balmy Venus, but if it involves pulverising the surface, we need to be extracting all the scientific information from the untouched wilderness area as we do it, because a lot will be lost forever otherwise.
