I had it right the first time, actually -- it is possible.
There is a lack of any example of it in the docs. And, references to
CREATE COLLATION right under "23.2.2.2.2. ICU collations" in the docs
are under the title "Copying Collations". That threw me off.
I think that we are entitled to assume plenty about what collations
ICU makes available, at least per version.
