Looks like Monch already answered - but yeah, there isn't really a way to do interwiki transclusion (besides from Central).

Technically there is this example, but as you can see it serves no practical purpose because it transcludes the whole webpage, not just the parsed wikitext.

It is also technically possible to use JavaScript to fetch and parse a page or template from another wiki, e.g. my post on Thread:487225. This is different from transclusion (transclusion would be better), and I advise against doing it, but it does work.

Basically, I would stick to Monch's suggestion of just transcluding your template from Central. There isn't really any "good" alternative.
