Not yet, he has fought pretty weak opposition and I have a hard time ranking him over many more proven fighters. In reality he's never fought an elite fighter- It's not really his fault though, the competition in the lower weight classes is awful (even guys like Cazares are pretty bad). Don't get me wrong though, I still think he is in the top 10-15 area.
Ivan could be at 10 like Doug Fischer said. Calderon wants to go up to 112, it will be hard as hell since he doesn't have the power but if he fights Solis and beats him, there could be a case for him going up in the P4P rankings. After all Solis lost to Dieppa and Calderon won against Dieppa 120-108. Only time will tell, he can't fight in 120 days because of the cut against Hugo.
You overrate the hell out of him based on his success against C level opposition. He's a limited fighter who'd likely get overwhelmed by anyone that could be considered elite. Very good at what he does, but his style is an example of one that usually only works when either the opponent plays his game(such as an inept D level fighter like Dieppa) or simply has no skills(Cazares). He's very slick, and great to watch when faced with the level of opposition he's faced throughout his career, but he's just not nearly versatile enough to be thought of as highly as he is. I wouldn't favor him over any of the elite 105-108 pounders throughout history, aside from Niida.
