I fixed the C-v case (at least partially), because it was a low-hanging fruit. But the general solution, if it's at all possible, is too complicated, and I see no reason to jump through hoops for such obscure use cases. We try very hard to preserve the column during C-n/C-p, and that should be enough. So I'm closing this bug report.
