If they want Kane to have any bit of credibility at all against HBK, Kane really needs to beat Matt, even if it's with Lita's help or whatever.
In 2004 Kane was tossed out of the Rumble just because of being distracted, has lost to The Undertaker, Tajiri beat Kane by count out, lost to Edge, lost to Benoit, lost to Benoit again by submission, Matt Hardy beat him in the No DQ match, Chris Jericho beat him in a No DQ match, and has lost to various guys like Eugene by DQ.
It seems like the only guys that he can even beat anymore are the Mavens of the world.
