I do get where Khali is coming from. But if they did it the way you say, then what cracker said would happen.
What they could have done was have a Angle vs Booker for a while which Booker loses, but because of something like Kurt used the ropes to pin him. Then gets a rematch at next PPV for the title. Wins. Then, maybe even another match for title next ppv, where after a LONG match he retains the title. Then after Booker gives out a chalange to any TNA star who wants the title to come out... First they could have done it with Robert roode, which would end up being a great match like Kaz vs Kurt was, but Booker wins. Then next PPV another challenge where another mid carder gets the push, maybe james storm, or maybe just have cage which would be nice to see, i am not sure about this one.
Finally when he issues the next chalange you have joe come out. You have him say things like the past few months he has had it easy and that he was the one who deserved the title shot more than anyone! Have him go all crazy and shit. Booker accepts, great build up over impacts and to a great PPV where Samoa Joe becomes Champion!!!
I don't know about what you guys think, but i just came up with this as I was writing away. This would BOTH milk Bookers star power, AND he would accomplish what he wants, which is putting over TNA talent. Looking back at what i propose, he makes other TNA talent look good by them coming close to beating him. In a sense he would make them famous
Then they can go and do something like Booker vs Sting

ahh that would be nice
I would have Samoa Joe keep the title for at least 4-6 months before dropping it to another TNA star. I highly recommend that star to be AJ styles. AJ is a top wrestler, and now they gave him a character and he can speak on the mike and is funny. By then he will be the total package
Sorry for rambling on for so long. That's just what I would like to have seen. Of course it may have been slightly different once more time gets put into refining my ideas.
