Muslim clerics and other faith leaders should be sent into state schools to teach children about religion, according to a teachers' union.
Pupils should also be given the time and facilities to pray during the school day, it said.
The system drawn up by the National Union of Teachers would replace traditional religious assemblies - which must be broadly Christian - as part of a radical overhaul of faith-based education in England.
In a new strategy document the union said that a more liberal approach to religious worship was needed in schools to cut demand for separate Christian, Jewish, Muslim, Sikh and Hindu state schools.
It also called for the relaxation of school uniform rules to allow pupils to wear religious symbols such as bracelets and headscarves.
The spread of schools catering for individual religions was "unjust and unsustainable" and risked undermining the Government's drive to promote race relations, the union said.
Steve Sinnott, the NUT's general secretary, said: "You could have imams coming in, you could have the local rabbi coming in and the local Roman Catholic priest. If there were opportunities where they all talked together to the youngsters, what a fantastic example that would be."
The policy document was formally adopted by delegates at the NUT's annual conference in Manchester.
It says that "reasonable accommodations" should be made to meet the religious needs of all pupils. Faith schools should also abide by the rules.
Last night, the Church of England opposed the plan, saying that "religious instruction belongs with religious institutions".
John Dunford, the general secretary of the Association of School and College Leaders, said: "I would have thought this plan could compound the problem if the people coming into schools were offering extreme views - how would you have any control over what was being taught in your school?"
The union also said that local authorities should take control of all state school admissions, removing the right of faith schools to choose their pupils. Local admissions policies should "neither privilege or discriminate against children on the basis of the beliefs or practices of their parents", the document said.
There are 7,000 faith schools in the state sector in England, many of which are among the most popular schools, with many appearing at the head of official league tables.
