if you are talking about the Islamic religoun, i think you could. if you live in the united states regardless of the religious sector you claim to be, we all pray in the same Masjid (Hanbali, Whabi, Hanafi, zaydi, or Shei'a). regardless of the minor differences the bases of prayer and how we pray is the same. Islam is just Islam, there should be no mazhab in Islam.
(i personaly don't think there is a masjid just for Hanfi mazhab, or somthing like that, at least in the state) :) hope i helped
