There's more to geoengineering than just aerosols. Ultimately, it'll be about giant mirrors and barriers in space to modulate the Sun's radiation in various places. It may sound fantastic, since these are huge surfaces involved, but you can block or reflect the Sun's light with very thin materials, which can be folded up on their way up.
