HHH in 2001?

 Had HHH not torn his quad in the spring of 2001, what were the long range plans for his and Austin's "2 man power-trip" team?  I'm just assuming they would have broken up and feuded eventually.  Also, would the WCW/ECW Invasion have gone a bit differently with a healthy HHH?  

The long term plan was HHH going babyface and winning the WWF title from Austin at WM18.  I doubt his health would have affected the Invasion much one way or the other, to be honest.
