Any paint will maintain the underlying texture, so long as it's applied in a thin enough layer. I'd likely just go with a few coats of diluted acrylics. If you want to change the texture, instead, use neat house paint (latex/emulsion) and stipple it on for a popcorn stucco sort of effect. A light sanding afterward will knock off the high points, leaving something that looks (at scale) like it was troweled on - perfect for daub, IMO.
