Yes. It would piss off the fandom a lot and be a clear statement by DC that one matters more than the other.

Besides, there's no real reason for something like that. Clark's family of legacies is pretty small; Jon, Kara, Conner. We can include Steel and Power Girl but neither have been a part of Clark's world for a long time. Now, I'm one of those fans who thinks Superman should largely remain a singular being; we don't need an army of child Super soldiers running around like we have a billion Robins and Batgirls. Superman should be...bigger, he shouldn't be something you can legit join up with or sidekick for. But that thematic resonance goes against marketing and business sense (the "S" sells, so you use the "S" more and offer alternatives to pull in more customers, like Diet Coke and Coke Zero). But we don't have so many legacies we need to cull them, and both Jon and Conner offer unique perspectives that can fuel stories.

Wiping Conner of the board for Jon was questionable enough (though I understand wanting one single Superboy for fans to focus on while Jon got his feet under him). Killing one off wouldn't do the fandom or DC many favors. At least not long term. A temporary death can be good for business, but nothing more permanent.
