We took a similar approach in several papers. Including even one pattern in full often breaks your word limit. On the other hand, some of the details in the pattern might be technical or formalistic and not interesting for the journal readers. A good summery and some diagrams, along with a link to the the full version on the web should be fine. If you report on a collection of patterns, it may be useful to add a map of their relations.
Having the patterns in a good repository helps, as it is something you can reference. I would also argue that the patterns in the repository includes unprintable elements, and so it it justified to send readers to the web.
