Could the Citadel be moved every cycle? Look at where it is situated this cycle, compared to the known homeworlds: most of them are around what Star Trek would call the Alpha Quadrant, the lower left quarter from the perspective of the Galaxy Map (or near that region). Only a few are far away: Rannoch, Kar'shan, and the Vorcha homeworld (or is it? I don't remember clearly where it is).
I think that, after every cycle's reap sweep is done, the Reapers did a survey of which species are likely to be the starfarers of the next cycle, averages out where the astropolitical center would be, and then moves the Citadel there.
