I do just the opposite: make (some) categories behave more like custom
taxonomies. This way, I can use the wonderful category__and parameter of
get/query_posts (all I got with taxonomies was just a single rewrite, so
querying two different taxonomy terms at once was a real headache). (How
I do this exactly is, methinks, out of the scope of this question, but
if s/o is interested in the details, mail me or whatever).
For this specific problem of yours, I create a Page in the desired
location, which has a template just like category.php (actually, it's
the very same category.php, with a header to identify it as Page
template, and a selector to retrieve query_var('cat') or a custom field
in the Page, whatever applies). Also, some metadata needs to be added to
the category; I use a custom termmeta table, but that can be saved as an
option, just like parents.
As a final step, hook to get_term_link, and return the Page permalink
instead of the default category permalink, if the category happens to
link to a Page.
So, you can have
... but if you wanted, you could even have...
... that is, add some higher-level all-taxonomy wrapper category (useful
if, say, you have "system" taxonomies like content-type, and "content"
taxonomies like "foo", "bar", "barring foo", etc.), skip some children
or "flatten" some levels (you could have movies/index/t/things-to-come
"flattened" as movies/things-to-come , and also movies/index and
Anyway, maybe this trick can do for you. Create a Page template that
reads some custom field/whatever to link it to the term, and hook to
get_term_link: that could do the job.
