For making things like IP fragmentation ids and other similar protocol
elements unpredictable, it would be useful to have what I'll call a
cryptographic ergodic sequence generator -- that is, a generator that
will produce a sequence of n bit numbers such that there are no
repeats until you pass

I'm sure that it would be possible to design a Feistel-based block

There's no need to exclude odd n.
I know the typical superficial textbook describes
the Feistel trick in
