Luffy is smarter than Kid and has a better personality. Of course he is going to attract more people with his behavior than Kidd will.
And he got his lessons in Sabaody and learned from it. He decided to train and his crew actually prepared for the NW.
He also has greater potential and a far stronger crew. I mean he doesn't even have to participate if Kidd's crew goes after his crew, Zoro, Sanji and Jimbei can take care of them.
So the answer is no, Kidd is not a realistic version of Luffy, he is a just hot headed guy who overestimate himself and his crew. And his crew is also not balanced as nobody would contest the bad decisions Kidd take. We have seen Nami or Zoro calming Luffy down whenever his decisions aren't the right ones and he respects them enough to listen to them.
