allow rearrangement. Added rule: Each link in the chain must be a
word from a language different from that of all of the other links.
Thus
COO (English)
oko (Polish)
koi (Finnish)
KIE (Esperanto)
On a slightly more serious note, I had some more time to consider
your previous suggestions for rule enhancements.

reduced if all of these were to be applied (esp. all letters
occupying all posns).
However, I think that the following subset is not unreasonable:
1. One (and only one) letter is to be changed at each turn.
2. No letter may occupy the same position that it did in the previous
turn.
3. Where the Doublets have letters in common, those letters cannot be
retained during the entire chain - they must be swapped out (and
back) at some point. Furthermore, the letter substituted for the one
in common cannot be the one that is subsequently resubstituted by
that common letter.
I can hopefully illustrate these rules a little better by applying
them to your original challenge:
TANK
ante
seat
arts
oast
stow
owls
bowl
flow
golf
FLAG
('W' is initially sub for 'A' which then resubs 'O').
I think it likely that we can shorten this chain and I'm sure you'll
try (I know I will :-).
Till then

solution!
