Invite Cornish, and Jersey sides into the Celtic Rugby Union League

At present in 2020, there is a rugby union league for Scottish, South African, Italian, Irish and Welsh sides. It is called the Pro14.
How about inviting the Jersey rugby union side, and Cornwall to enter teams into the league.?

It is debatable whether Cornwall is English. As some people in Cornwall are happy for Cornwall to be seen as part of England. But some see Cornwall as a separate nation.
But Jersey does not see itself as English. Jersey see themselves as a strong identity crown dependency.
Cornwall and Jersey are strong rugby regions, and travelling to these two regions would not be difficult as both have good logistic connections.
It would be great fun to add them to the set up.
Also I think Cornwall should have their own national rugby side that play in the second tier of European national rugby. Cornwall going independent would not damage England, but would another great nation to European and World Rugby.
