In two of those years, the eisteddfod would be held at permanent bases, possibly in north west Wales and west Wales, while in the other two years it would alternate between temporary homes in north and south Wales as it currently does.
Meanwhile, teachers at Cardiff's Fitzalan High School have told BBC Wales they will be withdrawing from all competitions at this year's Urdd National Eisteddfodin Cardiff as a result of another poem - called Bwyd Od (Odd food).
The eisteddfod's shadow governing body met in Aberystwyth on Saturday and said this year's festival in Newport, south Wales, was already showing signs of losing a large amount of money.
