It's worth trying, the principle works.
Indeed I even felt it from paragliding, how large dark patches form rising convection cells, later fluffy clouds.
Unstable air is also needed, which is rare within the descending side of big Hadley cells - why these areas are deserts.
Otoh the big deserts were greener in the past, so it might be possible again.
