Just tell me what you think of this idea, is it stupid or feasible. I don't think it's possible, but I thought it'd create an interesting discussion.

Reminds me a naive college buddy of mine, who, whilst sitting in the backseat of my Honda Civic on our way to Sunday Liturgies, would tell me about his life-long dream to (a) write a series of best-selling sci-fi novels, (b) become filthy rich, (c) use his fortune to amass a small army of African mercenaries, (d) lead said mercenaries and a like-minded Orthodox priest on a tactical amphibious raid of Istanbul, and (e) thereby capture Agia Sophia for a period of time long enough for the priest to finish celebrating the Divine Liturgy that Mehmed II's invaders had interrupted.
This whole project would be worth the trouble, of course, because Turkish (and Greek) lore says that if that Liturgy is ever completed, then such will signal the end of the Turks' occupation.
Thus, this young friend would sigh, we Orthodox could regain the City.
