Cup involving 11 Celtic, 9 South African and 4 Italian teams was announced in 2005, but the idea was abandoned because of financial issues on the European end of the deal and changes in the leadership of the South African Rugby Union (SARU). London Welsh expressed interest in 2006 in joining the Celtic League if promotion and relegation were to be removed from the English Premiership. In February 2009, South Africa was rumoured to be negotiating entry of its current Super Rugby teams into the Celtic League, to take effect when the media contract between SANZAR and News Corporation expires after the 2010 season; these rumours were immediately denied by SA Rugby, the commercial arm of SARU.

In September 2016, it emerged that Vancouver and Houston may be target cities, primarily due to weather considerations, though the distance from the other teams may make that more of a challenge. While the North American plan remains active, media attention turned in 2017 toward a new possibility of South African teams entering the competition. Following the decision of Super Rugby organiser SANZAAR to drop three teams from the competition (two from South Africa), multiple media reports indicated that the two likeliest South African sides to be axed, the Cheetahs and Southern Kings, could be added to Pro12 as early as the 2017–18 season. A later BBC report indicated that the Cheetahs and Kings would be added once their removal from Super Rugby was formally announced on 7 July, though neither Celtic Rugby Limited, the
