Sorry Gambit, We agree on a lot but not this. The capacity is what makes the advantage. Can't change that.
Yet, of all the good ideas people are expressing here, the stadium thing seems to be the one that has actually had some discussion going on about it in official circles. I have no reason to doubt PitV on this. Two people on this board I never doubt: PitV (on physical plant issues) and Tom McA (on what is going on behind the scenes.)
I can see that it would be a tough initiative to tackle, though.
