The Celtic Challenge will no doubt play a huge part. The cross-border competition is now in its third year, with Lightning and Thunder already producing internationals.
The ambition at the WRU is that the two regions could even entice Welsh players struggling for game-time to return home.
“It was so amazing for myself and so many of the other girls, it’s another opportunity to play,” said Metcalfe.
“It has grown so much in the past two years and I know this year is going to be even bigger again. It would be amazing to be part of that as well.”
As part of its recent consultation, the WRU said it would provide extra funding for the two sides – along with a new four-club league, a national academy and player development centres.
“This is a long term commitment by the WRU because we can see the opportunities ahead,” said Bennett.
“We need to ensure we are providing a future for players, for eight-year-old girls just as we do for eight-year-old boys who want to pull on the jersey and play for Wales.
“That is through a pathway and a system that is visible, coherent, accessible and delivers the success that we so desperately want.”
