A National Stadium for Scotland at all Sports

 Should there be a national sports stadium for Scotland,  for all sports. 

The Welsh have the Millennium stadium, that can house over 70,000. 

If Scotland was to combine the  national stadiums for rugby and football, they could build a stadium that could house 70,000 to 80,000 for rugby and football games. 

I do not mean yet. As the present Murrayfield and Hampden, still have decades of life left in them.

But when it is time to develop new stadiums, maybe next time they should combine for a national stadium for both sports? 

This new stadium could host bigger capacities, with more revenue put behind them, from both major sports of rugby and football. Perhaps the government could own it, and pay for it's construction.
