Should Cornwall have a national Rugby Union and Rugby League side?

I think Cornwall should have a national rugby union side competing in the international competitions and attempting to qualify for the World Cup. Cornwall has a strong regional or national identity. It also has placed rugby union as it's national sport.
Some people see Cornwall as a nation, some see it as a region of England.
I know that is a controversial issue and should be decided by people in Cornwall. But I think taking Cornwall away from England in rugby would not damage England, but would create another Celtic nation for people to in the Celtic lands to cheer on.

So imagine Cornwall qualifying to play for the World Cup or being promoted to the six nations. They could be as strong as Samoa or Fiji, in my view.
