Matt will post some more pics later, the problem with water puddy is what you described it doesn't have the sheer stringgth of hydracal type plasters my self i use US gypsum A-11 hydacal first choice after that it's statuary hydracal or hyrda stone(very hard and tough when set up ). as for scribing after casting its not needed if you use a wall form with windows opinings cast in (oppitional) i have used copper foil(from craft store) it can be imbossed with a stone patteren then cut to fit in the wall mold , them pour plaster on it , there will be some seepage around window openings . think i still have a wall i cast in shop some where will post pic if i fime it later.
