The server should map in both ways, i.e. reflect changes to XEP-0191 into the privacy lists, and also reflect changes in privacy lists to block lists.
In this specific case, the server would modify the privacy list by adding a rule (before the old rule), which allows the removed JID:
value='tybalt at example.com'
The server would then allow traffic from this user, but would still block everyone else from the "Enemies" group.
Such mapping in both directions can probably be complicated, but it shouldn't be impossible with well defined mapping rules.
Generating a block list from a privacy list should be easy, because it's just a small subset.
Merging changes in a block list to an existing privacy list (as in the example above) is more tricky, but certainly doable.
