That's a *lot* of extra columns for such a marginal feature. More likely we'd do something like log a blob that has a serialized list of everything changed. (This would require actually figuring out everything that was changed, of course, which already complicates things and probably slows them down.) If we want to revert, we'd load up the blob and build the queries from it.
That sounds feasible, and allow blobs to expire after a certain length of time unreverted if the space gets onerous.
What, a few kilobytes per rename? At a handful of renames per day? Not likely to be a problem.
