The idea has taken off at the European Championship, with Belgium and the Netherlands co-hosting in 2000, Austria and Switzerland in 2008 and Poland and Ukraine in 2012. The next tournament in 2020 has been designated as Pan-European and is due to be staged in 13 cities in 13 counties.
Swedish FA chair Karl-Erik Nilsson quickly backed co-hosting for the World Cup too.
'It's a good idea, and Europe has of course previously worked in this way on the European Championships,' he said.
'We are used to it and it works well, it makes it possible for more countries to arrange (tournaments), and in that way it is positive.'
Brazil's Maracana, which staged the last World Cup final in 2014, has become unusable in recent months, sitting with rusting gates and with a badly damaged playing area following a dispute over repair costs and redevelopment.
