Please wait and hold your judgement until it happens. Something similar to this already exists in Victory Park in Moscow for when they designed and built the park a Church, a Synagogue, and a Mosque were built at different places in the park. It is not the creation on one syncretic religion. I think there are too many people here who see any cooperation or civility between the Orthodox and other faiths as syncretism.
If you knew anything about Ufa, you would know that it has a high Muslim population, just like Kazan (which has a Cathedral and Mosque in its Kremlin). If the Muslims want a mosque, they will build a mosque. It's better than a war where the Orthodox loose and have their churches turned into Mosques.
