Ismaili will face Haras Al-Hidoud in the quarter finals on Friday, and if they win they will face the winner from Ahli-Gaish clash in the semis.
The Dervishes chairman Yahia Al-Koumi announced that the club is ready to bear the EGP 30,000 fee of acquiring a Non-Egyptian refereeing staff if the game went on.
Al-Koumi said that the club means no disrespect for Egyptian officials, but they aim to prevent controversy from the usually tense game between the arch rivals.
Egyptian champions Ahli's two-year unbeaten run was ended by Ismaili with a thumping 3-0 league win in January, and the Dervishes repeated the achievement with a 1-0 win in Ismailia last month.
Ismaili, who were the only team to beat Ahli twice this season, consider the Egyptian Cup title as a top priority.
