For a long time I have sort of wanted some variation on this. I wonder
if your plan can be generalized in a sensible way to accomplish my idea.

Suppose I run some long-running process. It delivers its output to the
tty. After a while I realise that this was a mistake; I want the output
redirected to a file instead. Killing the process and restarting is not
an option (too much time already spent on the task, or whatever). How to
do that?

The same thing, but the other way around. Or with stdin. In other words,
changing the actual files that file descriptors are connected to.
Possibly even plumbing a stdout and stdin together with a pipe.
