Well, at some point (if we believe DC ONE MILLION) Kal-El will leave Earth to journey among the stars when he loses all those who are closest to him to the ravages of time (Kal will live to see the 853rd century. Wowzers. :shock: ), but in his place will rise his heir and founder of the Superman Dynasty, Superman Secundus. Now, whether or not this is Kon is still kind of up in the air, but I have a sneaking suspicion it's him.
Your idea of Kon going off and forging his own superheroic identity does sound interesting though. Maybe you could put it together as a fanfic for a site that focuses more on the post-Crisis Superman Family.

I'm afraid DC One Million, Superman One Million contradicts that.
Superman Prime sought his descendant, the blood of his blood, in that book. The Justice Legion A Superman also noted that Lois is the co-founder of the Superman Dynasty.
IOW, Superman Secundus is supposed to be the real son of Superman Prime and suppositions that he's Kon-El/Conner Kent are simply wishful thinking unsubstantiated by the published books.
OTOH, Johns is retconning the Westfield DNA link to be Luthor instead so anything is possible if DC/writers shift gears. But established book evidence makes it clear it's not Connor. Indeed, Superboy One Million establishes a very different kind of legacy for the Cadmus Superboy that's separate from the Superman Dynasty. How about the OMAC (One Millionth Actual Clone) Superboy of that line?
