You'd need to distract Alhiera (changed her name slightly and major overhaul of her CS) somehow so she wouldn't be able to set the elements against you first, if not your invasion force will be effectively slaughtered by the desert and the further in you go the more problems with supply lines you're going to have. (There's naturally also the problem of heat, which has adverse affects on humans, animals, and war equipment and not to metion the nasty sandstorms which hot with little warning)
