Should the Jets attempt a Sanchez for Rivers swap?

The San Diego Chargers have just dropped their 5th in a row and now sit at 4-6. They are currently in last place and 2 games back. Barring winning out the rest of the season, or even 9-7 and somehow get a playoff birth, I think Norv Turner will finally be fired. Further, I suspect that there may be some changes coming in San Diego. Would the Chargers be willing to get younger at the QB position?

Rivers is having an off year, but still is in his prime at 29. He is a borderline elite QB and a proven talent. Then we have Sanchez. He is still a marginal QB on a team built to win now. He still has a ton of upside... but still is not consistent enough.

So I pose the question, could Philip Rivers be had? If so, how much should the Jets part with to get him? Would the Chargers trade both top 2004 QBs to both NY teams?
