Love him or hate him Morsi is the legitimate president and the military coup that brought him down was an illegal act. If El Baradei is appointed as some kind of stand in leader then he is an illegal leader. The elected president did not step down the military arrested him and then installed El Baradei as an interim president. He is the man they want to have win any future election so rather than the military themselves take power in the interim they appoint their man which is not only an attempt to build up his support so when elections do happen he will have an unfair advantage but also a man who is liked by the west might help them turn a blind eye to the fact he is there as the result of an illegal coup. Fact is if Egypt wants democracy they need to stick it out with Morsi until elections are held and then decide who they want because otherwise they don't have a system of democracy they have a mob rule system with the military supporting the mob rather than their commander in chief.
