The exact setup you asked for is not currently possible because `templatedir`
only takes one value, but you can get the same practical result with an underlay:

* Create `/Users/XXX/config/ikiwiki/common-files/` or something (the exact name
  is not significant, use whatever you want)
* Put your templates in `/Users/XXX/config/ikiwiki/common-files/templates/*.tmpl`
  (it has to be a `templates/` subdirectory)
* Add the [[plugins/underlay]] plugin to the `add_plugins` config option
* Add `/Users/XXX/config/ikiwiki/common-files` to the `add_underlays` config
  option (same syntax as `add_plugins`)

This is priority 2 from your list: it's \"less important\" than the `templates/`
subdirectory of the `srcdir`, but \"more important\" than the templates shipped
with ikiwiki.

If you create non-template pages or attachments in that underlay, they will
also be considered \"less important\" than pages or attachments of the same
name in the `srcdir`, but \"more important\" than ikiwiki's `basewiki` underlay.
I use an underlay like this to make
[smcv.pseudorandom.co.uk](https://smcv.pseudorandom.co.uk/)
and [www.pseudorandom.co.uk](https://www.pseudorandom.co.uk/)
share a stylesheet.
